This presentation addresses the why, what, and how to protect inventions from the vantage point of the early-stage, pre-financing, start-up company that is interested in patenting its inventions and developing an intellectual property portfolio that maximizes the company's valuation and sets it up for success during the intellectual property due diligence that accompanies financing rounds, corporate partnerships, commercialization, and merger and acquisition.
Biotechnology Patents: Disclosure Requirements under 35 USC 112. Discusses case law development of the enablement and written description requirements from In re Wright (Fed. Cir. 1993) through Ariad Pharmaceuticals v. Eli Lilly (Fed. Cir. 2010), including the origin of the "super enablement" requirement in Regents of the University of California v. Eli Lilly (Fed. Cir. 1997), the thought provoking dissent by Chief Judge Rader in Enzo Biochem v. Gen-Probe (Fed. Cir. 2002), the paradoxical "nascent technology" holding in Chiron v. Genentech (Fed. Cir. 2004), and the risks of relying on functional claim language from Rochester v. Searle (Fed. Cir. 2004). Practice tips are provided for avoiding the pitfalls in patent and claim drafting in view of these seminal cases.
Biotechnology Patents: Utility and eligibility requirements under 35 USC 101. This presentation follows the historical development of the utility requirement from the early 19th century case Lowell v. Lewis (MA 1817), the origin of the specific, substantial, and credible standard for a patent disclosure from Brenner v. Manson (SCOTUS 1966), and the modern application of the Brenner standard for biotechnology patents in In re Fisher (Fed. Cir. 2005). Biotechnology eligibility requirements are discussed from the early Supreme Court case Funk Brothers v. Kalo, the seminal biotechnology Supreme Court case Diamond v. Chakrabarty (SCOTUS 1980) where the court holds that statutory subject matter includes "anything under the sun that is made by man," through the recent Supreme Court decision in Myriad v. ACLU (SCOTUS 2013) where the court held that diagnostic method claims and nucleic acid claims that read on products of nature are patent inelibible. Practice tips are provided to ensure that patent claims avoid the exceptions of 35 USC 101 and withstand scrutiny during litigation and business transactions, such as licensing.

Maximizing Pharmaceutical Patent Life Cycles: Strategies to Avoid Obviousness...Rachel Hamilton
For over a decade, American Conference Institute’s (ACI’s) Maximizing Pharmaceutical Patent Life Cycles and Biotech Patents conferences have brought you up-to –the minute legal, regulatory, and policy information concerning small and large molecule drug products. In deference to the legacy of these iconic events and your revered opinion, ACI proudly presents this new program on Pharmaceutical and Biotechnology Patent Life Cycles and Portfolio Strategies. This conference will give you a comprehensive and thorough picture of how small and large molecule products—as well as diagnostics—operate in a world not only governed by PTO and FDA-related laws and regulations, but also against the backdrop of Hatch-Waxman, BPCIA, iconoclast Supreme Court decisions affecting the future life sciences IP, and Health Care Reform. Our stellar faculty will provide you with insights and strategies relative to life cycle management, portfolio strategies, brand optimization and new product development as well as the thoughtful and targeted commentary and in-depth analysis that you have come to expect from ACI’s industry-leading life sciences IP conferences.
This presentation discusses the historical context for the recent court decisions that affect the patent eligibility of biotechnology inventions, including those directed to genes, cDNAs, proteins, antibodies, and diagnostic methods. Discussed are the early Funk Brothers and Chakrabarty decisions as well as the Lab Corp, Bilski, Prometheus, Classen, and Myriad court opinions. The impact of the court holdings on the future development of biotechnology inventions, in particular personalized medicine inventions, is analyzed as is the erosion of the requisite incentives of innovative companies to invent and commercialize in areas where patent protection is less certain.
The second breakout session was directed to attendees in the information technology (IT) and biotechnology sectors, with discussion about the recent Alice v. CLS Bank Supreme Court decision.
July’s practice group lunch included an overview of recent decisions, the Court of Appeals for the Federal Circuit, and the United States Supreme Court. The Supreme Court addressed a number of patent law topics this year, including the standard of review for patent claim construction (Teva Pharmaceuticals v. Sandoz), royalties on expired patents (Kimble v. Marvel Enterprises), and defenses to claims of induced infringement (Commil v. Cisco). The initial wave of appeals in post-issuance proceedings provided by the America Invents Act are now being decided by the Federal Circuit. These include cases involving whether the decision to institute is reviewable (In re Cuozzo Speed Technologies) and discussion of the claim construction standards that apply (Microsoft v. Proxyconn). The relationship between administrative challenges and related litigation is also an evolving area (ePlus v. Lawson Software).

This analysis shows how IP, regulatory, and marketing strategy have to interfere for maximizing the lifetime of IP protection in pharmaceuticals. In contrast to mechanical inventions you can use special aspects of chemical /pharmaceutical patents like medical use or SPCs and PTE or variations in formulation to optimize your product protection. Using the example of an active ingredient it is shown how filing strategy, product development and finally IP life cycle management can be combined to achieve the maximum market success.
Our presentation for Pharma Sector.
Problem statement: You are Pfizer and your major blockbuster drug, Lipitor ($12 bn in sales in 2008, ~20% of your total revenue), is going off-patent in 2011. A decline in the sales of Lipitor is inevitable and you are looking to make a major move into emerging economies where growth in pharma sales is the highest. How would you go about doing this?
The course covers the following topics:
* General Intro to IP Rights
* Patenting Timeline and Costs
* The Patent Description
* Approaches to Claim Drafting

This article discusses changes in the patent law obviousness doctrine after KSR and provides strategy recommendations for protecting biotechnology inventions
Think your innovation is sufficiently enabled to secure, defend, and assert your patent rights? If it’s a biological, chemical, or emerging technology invention then you might want to think again. In today’s episode we’re looking into how to get more predictable results from the unpredictable arts.
Some technologies, like those rooted in physics and mechanics, are considered “predictable” by the US Patent Office, while others, like biological and chemical technologies, are generally considered “unpredictable.” It follows that the amount of disclosure required to enable an invention is related to the predictability of the technology, and so-called unpredictable arts require more description to teach a reader how to “make and use” the technology. Similarly, emerging technologies, being less well known, also require more disclosure to be fully enabled.
In this month’s episode, David Jackrel, President of Jackrel Consulting, leads a discussion along with our all star patent panel, exploring enablement for the unpredictable arts and emerging technologies. The panel discusses peculiarities of patenting unpredictable art and emerging technologies, with a focus on modern case law and statutes to arrive at a set of best practices for getting more predictable results when patenting these technologies.

The Federal Circuit Review monthly newsletter is now available. This month’s newsletter covers the latest decisions handed down from the Federal Circuit:
Otsuka Pharmaceutical Co. v. Sandoz Inc.; In Re Youman; In re Montgomery; Leader Technologies, Inc. v. Facebook, Inc.; Apple, Inc. v. Samsung Electronics Co., Ltd.; In Re Baxter International, Inc.; Mintz v. Dietz & Watson, Inc.
We’re leading off Season 3 with a close look at a Supreme Court patent case that could have profound impacts on the invention enablement problems we covered heavily in Season 2. SCOTUS is set to hear opening arguments in Amgen v Sanofi on March 27th. For the first time in over 75 years, the Supreme Court is evaluating the meaning and scope of the enablement requirement. For those who’ve been following along, you’ll know that this has become one of the bigger issues plaguing patenting and especially so in the life sciences.
Dr. Ashley Sloat, President and Director of Patent Strategy at Aurora, leads our discussion today along with our all star patent panel, exploring the scientific background around antibodies necessary to understand the claims, a brief case history of Amgen v Sanofi, an overview of the enablement factors and tests that have been historically applied in courts and how they might apply to this case, and a discussion around open questions and the potential unintended consequences of the Supreme Court only taking up one-half of the two-sided enablement coin. This ends up being a really great, spirited conversation with panel members coming down strongly on both sides of the case with very compelling arguments – really highlighting the complexities and fundamental issues the court will have to face.

Life science patents have grown increasingly vulnerable to rejection and invalidation due to subject matter eligibility and enablement interpretations. The implications are staggering with over 80% of abandoned life science applications having a final rejection stating that the innovation did not include patentable subject matter. In this talk, we’ll explore how to avoid these rejections, understand the implications for new drugs, and provide practical tips for creating robust life science patents.
Attorneys Mauricio Uribe, Eric Forman and Vlad Teplitskiy present a Webinar focusing on strategic considerations for patent prosecution in the United States in view of the statutory requirements of Section 103.

• This presentation is for information purposes only and does not
constitute legal advice. Patent issues are fact-dependent and
require the assistance of counsel experienced with such issues.
This presentation does not establish any form of attorney-client
relationship.

4. 4
§103 in the 1952 Patent Act
• A patent may not be obtained though the invention is
not identically disclosed or described as set forth in
section 102 of this title, if the differences between the
subject matter sought to be patented and the prior art
are such that the subject matter as a whole would have
been obvious at the time the invention was made to a
person having ordinary skill in the art to which said
subject matter pertains. Patentability shall not be
negatived by the manner in which the invention
was made.
4
5. 5
Graham v. John Deere Co. (1966)
• In Graham v. John Deere, a test was formulated for the issue
of patentability under §103. Under §103,
– (1) “the scope and content of the prior art are to be
determined;
– (2) “differences between the prior art and the claims at
issue are to be ascertained;” and
– (3) “the level of ordinary skill in the pertinent art resolved.”
– And . . . “[s]uch secondary considerations as commercial
success, long felt but unsolved needs, failure of others,
etc., … may have relevancy.”
5
6. Federal Circuit’s Obviousness 6
Jurisprudence
• The Court of Appeals for the Federal Circuit (FC) was
created in 1982 to achieve doctrinal stability in patent
law.
• The FC developed the teaching-suggestion-motivation
(TSM) test:
– when prior art references contain different elements of a
claimed invention, the references can be combined to find
obviousness of the claimed invention only when there is
some teaching, suggestion or motivation to combine
the prior art references.
6
7. §103 and the TSM test 7
• In re Dembiczak (Fed. Cir. 1999)
– “Our case law makes clear that the best defense against the subtle but
powerful attraction of a hindsight-based obviousness analysis is rigorous
application of the requirement of a showing of the teaching or motivation
to combine prior art references.”
PRIOR ART “INVENTION”
• Obviousness cases are factually dependent, so some
results may be outlying and easily caricaturized.
– “As a trip to the checkout counter at most grocery stores will
reveal, the selection of ‘paper or plastic’ is a quite routine set
of alternative materials for bagging purposes.”
Roger E. Schechter et al., Principles of Patent Law 161 (2004).
7
8. 8
§103 and the TSM test
• §103 states that the analysis of obviousness is based on
whether “the subject matter as a whole would have been
obvious at the time the invention was made to a person
having ordinary skill in the art to which said subject
matter pertains.”
• Critics asserted that the emphasis on prior art as
opposed to the analysis by a person having ordinary skill
in the art (PHOSITA) relegated the PHOSITA to at best a
librarian and at worst an automaton. By elevating the art
above a creative PHOSITA, the standard for
obviousness was too low and approached
novelty.
8
9. Oral Arguments at the Supreme Court9
in KSR v. Teleflex (2007)
• U.S. Supreme Court last addressed obviousness in
1976.
• Scalia: “I agree with the Chief Justice. It is
misleading to say that the whole world is embraced
within these three nouns, teaching, suggestion, or
motivation, and then you define teaching,
suggestion, or motivation to mean anything that
renders it nonobvious. This is gobbledygook.
It really is, it’s irrational.
9
10. Obviousness standards in the U.S. -
10
“Goobledygook” evolves
• The U.S. Supreme Court held in KSR v. Teleflex that the TSM
test was applied by the FC in a narrow, rigid manner that is
inconsistent with § 103 and Graham v. John Deere.
• PTO provided 2007 KSR Guidelines, based on rationales for
finding obviousness detailed in KSR, which were
subsequently incorporated into the Manual of Patent
Examining Procedure (MPEP) at § 2141 and § 2143
• On September 1, 2010, the PTO provided “Examination
Guidelines Update: Developments in the Obviousness
Inquiry after KSR v. Teleflex
10
11. 11
MPEP §2143
• “KSR identified a number of rationales to support
a conclusion of obviousness which are consistent
with the proper “functional approach” to the
determination of obviousness as laid down in
Graham.”
• These rationales are detailed in Rationales A-G of
§2143 which is titled: “Examples of Basic
Requirements of a Prima Facie Case of
Obviousness.”
11
12. PTO’s Obviousness Rationales - § 214312
A. Combining prior art elements according to known methods to yield predictable
results.
B. Simple substitution of one known element for another to obtain predictable
results.
C. Use of known technique to improve similar devices (methods, or products) in
same way and the result would have been predictable.
D. Applying a known technique to a known device (method, or product) ready for
improvement to yield predictable results.
E. “Obvious to try”—choosing from a finite number of identified, predictable
solutions, with a reasonable expectation of success.
F. Known work in one field may prompt variations of it for use in same field or
different one based on design incentives or market forces if the variations are
predictable.
G. The teaching-suggestion-motivation (TSM) test.
H. Anything else that can be used to prove obviousness.
12
13. PTO’s Obviousness Rationales - § 214313
2010 KSR Guidelines Update:
Focus on additional guidance in view of decisions
by the Federal Circuit since the KSR decision,
including “teaching points”, in 3 of the rationales;
A. Combining prior art elements according to known methods to yield
predictable results (i.e. Aknown + Bknown => A-B)
B. Simple substitution of one known element for another to obtain
predictable results (i.e. Aknown => A’)
E. “Obvious to try”—choosing from a finite number of identified,
predictable solutions, with a reasonable expectation of success
(i.e. A-Z => obvious to try; A -∞ => invention

In re Omeprazole
• AstraZeneca found that alkaline reacting compound (ARC)
addition to drug core helped stabilize drug in storage, and that an
enteric coating was needed to keep drug from decomposing in
the stomach, but normal enteric coatings were known to dissolve
the ARC
• AZ determined that a water-soluble subcoating would keep ARC
intact but allow drug release in small intestine
WATER-SOLUBLE
CORE = DRUG + ARC SUBCOATING
ENTERIC COATING
16
17. 17
In re Omeprazole
• no prior art showed a negative interaction between ARC
and enteric coatings or discussed subcoatings, thus no
motivation to introduce a subcoating; not obvious
• even if there were motivation, a water-soluble
subcoating would not be obvious to try
WATER-SOLUBLE
CORE = DRUG + ARC SUBCOATING

In re Omeprazole
• 2010 KSR Guidelines “teaching point”
“Even where a general method that could have been
applied to make the claimed product was known and
within the level of skill of the ordinary artisan, the claim
may nevertheless be nonobvious if the problem which
had suggested use of the method had been previously
unknown.”
18
19. Practice tips for overcoming rejection
19
based on MPEP §2143 Rationale A:
A. Combining prior art elements according to known
methods to yield predictable results.
(i.e. Aknown + Bknown => A-B)
To address an obviousness rejection:
- argue that the results were not predictable
- argue that the problem was unknown
- argue that an unknown method was used to solve the
problem

artisan had reason to believe that some desirable
property of the mixture was derived in whole or in part
from the claimed compound, and separating the
claimed compound from the mixture was routine in the
art.”

Eisai v. Dr. Reddy’s Labs
533 F.3d 1353 (Fed. Circ. July 21, 2008)
• rabeprazole (Aciphex); PPI for ulcers, GERD
• prior art = lansoprazole, omeprezole,
Brändström
26
27. 27
Eisai v. Dr. Reddy’s Labs
• Dr. Reddy’s claimed rabeprazole was obvious because of
lansoprazole, omeprazole and Brändström’s core
• prior art (lansoprazole) contained a CF3 group in order to
increase lipophilicity, but rabeprazole has no F’s
• omeprazole not structurally similar enough
• no “reasoned identification of a lead compound” since the
F’s were removed, so lansoprazole not a valid lead because
no motivation to select it
• no other support to select leads other than lansoprazole
• thus, not obvious to make rabeprazole

Eisai v. Dr. Reddy’s Labs
• 2010 KSR Guidelines “teaching point”
“A claimed compound would not have been
obvious where there was no reason to modify the
closest prior art lead compound to obtain the claimed
compound and the prior art taught that modifying the
lead compound would destroy its advantageous
property. Any known compound may serve as a lead
compound when there is some reason for starting with
that lead compound and modifying it to obtain
the claimed compound.”

Proctor & Gamble v. Teva
• prior art = 2-pyridyl EHDP
• bisphosphonate art at the time was very unpredictable
• 3-pyr EHDP much less toxic, 4-pyr EHDP not active
• CAFC: no evidence that the structural modification was
routine in the art, so no prima facie case of obviousness
• even if a prima facie case had been shown, the
unexpected results would successfully rebut
• secondary considerations (commercial success and
meeting a long-felt need) supported nonobviousness

Proctor & Gamble v. Teva
• 2010 KSR Guidelines “teaching point”
“It is not necessary to select a single compound as a
“lead compound” in order to support an obviousness
rejection. However, where there was reason to select and
modify the lead compound to obtain the claimed
compound, but no reasonable expectation of success, the
claimed compound would not have been obvious.”

32
33. Altana v. Teva 33
• prior art compound was identified as one of the “more potent” of
18 compounds for which data was given
• additional prior art (Sachs) taught that the optimum pKa for PPI = 4
• additional prior art (Bryson) taught that the pKa of 3-methoxy
pyridine is closer to 4 than the pKa of 3-methyl pyridine
• CAFC: prior art compound was a reasonable lead compound from
which to pursue further development
• lower court’s decision for sufficient case of obviousness on merits
was affirmed (i.e., likelihood of success)
• Newman concurrence: evidence doesn’t establish obviousness, but
deference to lower court given in a preliminary injunction phase
33
34. Altana v. Teva 34
• 2010 KSR Guidelines “teaching point”
“Obviousness of a chemical compound in view of
its structural similarity to a prior art compound may be
shown by identifying some line of reasoning that would
have led one of ordinary skill in the art to select and
modify a prior art lead compound in a particular way to
produce the claimed compound. It is not necessary for
the reasoning to be explicitly found in the prior art of
record, nor is it necessary for the prior art to
point to only a single lead compound.”

35. MPEP §2143 Rationale B: 35
Practice Tips
B. Simple substitution of one known element for another to
obtain predictable results.
(i.e. Aknown => A’)
To address an obviousness rejection:
- don’t try to patent a particular single isomer of a racemic mixture
or mixture of stereoisomers if it’s known that the particular single
isomer has the desired activity, or use a really non-routine method
to do the separation
- try to find prior art that indicates your modification will cause the
compound to lose all desired activity
- don’t use a known lead compound to start from,
combined with known modifications
35
36. MPEP §2143 Rationale B: 36
Practice Tips, continued
B. Simple substitution of one known element for another to
obtain predictable results.
To address an obviousness rejection:
- if you have used a known lead compound and known
modifications, argue that there’s no reasonable expectation of
success for the claimed compound’s activity
- argue that the known compound/set of compounds would not
have been selected as “lead” compounds by the skilled artisan,
or that there was no motivation in the prior art to make the
specific modification

MPEP §2143, Rationale E
• Nine cases are profiled in Rationale E of the MPEP
and 2010 KSR Guideline Update
– Pfizer v Apotex (Fed. Cir. 2007)
– Alza v. Mylan Laboratories (Fed. Cir. 2006)
– Takeda Chem v Alphapharm (Fed. Cir. 2007)
– Ortho-McNeil v Mylan Labs (Fed. Cir. 2008)
– Sanofi v Apotex (Fed. Cir. 2008)
– Bayer v Barr (Fed. Cir. 2009)

38. 38
Pfizer v. Apotex
480 F.3d 1348 (Fed. Circ. 2007)
prior art: list of 53 FDA-approved
anions useful for making
pharmaceutically-acceptable
salts of drugs
(Berge, J. Pharm. Sci., 1977)
amlodipine besylate (Norvasc®)
invalid: finite number of pharmaceutically acceptable salts known,
for a reasonable expectation of success (US 4,879,303)
38
39. 39
Pfizer v. Apotex
• Claim 1 of U.S. Patent No. 4,879,303 recites: the besylate
salt of amlodipine.
• Background: At the time of the invention, amlodipine was
known as was the use of besylate anions. Amlodipine was
known to have the same therapeutic properties as were
being claimed for the amlodipine besylate but Pfizer
discovered that the besylate form had better
manufacturing properties (e.g., reduced “stickiness”).
Amlodipine besylate is sold in tablet form in the U.S. under
the trademark Norvasc®.
39
40. 40
Pfizer v. Apotex
• DC: not obvious
• FC: obvious as it was obvious to try
• Pfizer argued that the results of forming amlodipine
besylate would have been unpredictable and therefore
nonobvious. The court rejected the notion that
unpredictability could be equated with nonobviousness
here, because there were only a finite number (53) of
pharmaceutically acceptable salts to be tested for
improved properties.
40
41. Alza v. Mylan 41
464 F.3d 1286 (Fed. Cir. 2006)
• Claimed invention: sustained-release formulations of the
drug oxybutynin in which the drug is released at a
specified rate over a 24-hour period.
• For overactive bladder
Oxybutynin (Ditropan)
41
42. 42
Alza v. Mylan
• “Obvious to try” is not mentioned. However, Alza v.
Mylan is used as an example of “obvious to try”
rationale in MPEP §2143(E).
• Oxybutynin was known to be highly water-soluble.
The specification pointed out that development of
sustained-release formulations of such drugs
presented particular problems.
42
43. 43
Alza v. Mylan
• (1) Prior art patent to Morella taught sustained-release
compositions of highly water-soluble drugs, as
exemplified by a sustained-release formulation of
morphine. Morella had also identified oxybutynin as
belonging to the class of highly water-soluble drugs.
• (2) Patent to Baichwal taught a sustained-release
formulation of oxybutynin with a different release rate
than the claimed invention.
• (3) Patent to Wong taught a generally applicable method
for delivery of drugs over a 24-hour period.
– Although Wong mentioned applicability of the disclosed method
to several categories of drugs to which oxybutynin belonged,
Wong did not specifically mention its applicability to
oxybutynin.”
43
44. 44
Alza v. Mylan
• Federal Circuit: Because the absorption
properties of oxybutynin would have been
reasonably predictable at the time of the
invention, there would have been a
reasonable expectation of successful
development of a sustained-release
formulation of oxybutynin as claimed.

45. 45
Takeda Chem v. Alphapharm
492 F.3d 1350 (Fed. Cir. June 28, 2007)
• Claim 1 recites:
• The ethyl-substituted pyridyl ring
encompasses four possible compounds as the
ethyl substituent (C2H5)
is located at one of four available positions on
the pyridyl ring.
45
46. 46
Takeda Chem v. Alphapharm
• Claim 2 covers pioglitazone (the 5-ethyl
compound) which has the ethyl substituent
attached at the 5-position of the pyridyl
ring
46
47. 47
Takeda Chem v. Alphapharm
• Alphapharm asserted that the claimed
compounds were obvious based on a prior
art compound known as “compound
b.” Compound b possesses a pyridyl ring in
which a methyl (CH3) group is attached to
the 6-position:
47
48. 48
Takeda Chem v. Alphapharm
• District Court concluded that “there was no motivation
in the prior art to select compound b as a lead
compound for antidiabetic research, and that the prior
art actually taught away from its use.”
• DC also concluded that even if Alphapharm had
succeeded in making a prima facie case
of obviousness, such a showing would be rebutted by
the unexpected results of pioglitazone's nontoxicity.
48
49. 49
Takeda Chem v. Alphapharm
• DC and FC: nonobvious
• FC’s analysis:
– Alphapharm failed to shows that
Compound b would have been selected
as the lead compound
– Alphapharm failed to show a reason to
modify Compound b to achieve the
claimed compounds.
49
50. 50
Takeda Chem v Alphapharm
• 2010 KSR Guidelines “teaching point”
“A claimed compound would not have been obvious
where it was not obvious to try to obtain it from a broad
range of compounds, any one of which could have been
selected as the lead compound for further investigation,
and the prior art taught away from using a particular lead
compound, and there was no predictability or reasonable
expectation of success in making the particular
modifications necessary to transform the lead
compound into the claimed compound.”

Ortho-McNeil v. Mylan Laboratories
Fed. Cir. March 31, 2008
• topiramate (Topomax); epilepsy drug
• lower court permanently enjoined Mylan from infringing Ortho’s
product, and the FC affirmed
• Ortho was searching for new diabetes drugs, but found that a
synthetic intermediate (itself derived from DPF) for an anti-
diabetic compound was a potent anticonvulsant
O OH O OSO2NH2
O O O O
O O O O
DPF (di-isopropylidine fructose) topiramate
51
52. 52
Ortho-McNeil v. Mylan
• CAFC: a skilled artisan “would not even be likely” to
start with DPF as a lead compound to design a diabetes
drug
• hindsight analysis is inappropriate
• the subject matter as a whole must be examined at the
time the invention was made; not obvious
• secondary considerations also support nonobviousness
– powerful unexpected results
– skepticism of experts and copying
– commercial success
52
53. 53
Ortho-McNeil v Mylan
• 2010 KSR Guidelines “teaching point”
“Where the claimed anti-convulsant drug had been
discovered somewhat serendipitously in the course of
research aimed at finding a new anti-diabetic drug, it
would not have been obvious to try to obtain a claimed
compound where the prior art did not present a finite and
easily traversed number of potential starting compounds,
and there was no apparent reason for selecting a
particular starting compound from among a
number of unpredictable alternatives.”

Sanofi v. Apotex
Fed. Circ. December 12, 2008
• clopidogrel bisulfate (Plavix); blood thinner
• single enantiomer
• prior art = racemic mixture
54
55. 55
Sanofi v. Apotex
• CAFC: the separation of the mixture was not
routine or simple (salt with (+)-camphorsulfonic
acid/acetone)
• Apotex cited no reference that showed or
suggested a reliable method of separation for
analogous compounds
• success in the separation was unpredictable
• unknown before the separation which isomer
desirable
• KSR recognized hindsight bias as inappropriate
• not obvious to separate the enantiomers
55
56. 56
Sanofi v Apotex
• 2010 KSR Guidelines “teaching point”
“A claimed isolated stereoisomer would not have
been obvious where the claimed stereoisomer exhibits
unexpectedly strong advantages over the prior art
racemic mixture without the correspondingly expected
toxicity, and the resulting properties of the enantiomers
separated from the racemic mixture were unpredictable.”

57. 57
Bayer v. Barr
Fed. Circ. August 5, 2009
• drospirenone (Yasmin); oral contraceptive
• poorly soluble in water
• isomerizes in acid to a
compound with
undesired properties
57
58. 58
Bayer v. Barr
• prior art taught micronization to improve solubility in
water, but it also increased acid sensitivity
• enteric coatings known to protect oral drugs from
stomach acid, but also decreased bioavailability
• Bayer found that the micronized drug with an enteric
coating had same bioavailability as without the coating
• CAFC; prior art narrowed options to a finite number
of identifiable predictable solutions, so obvious
• Newman dissent; no reasonable expectation of
success here
58
59. 59
Bayer v Barr
• 2010 KSR Guidelines “teaching point”
“A claimed compound would have been obvious
where it was obvious to try to obtain it from a finite and
easily traversed number of options that was narrowed
down from a larger set of possibilities from the prior art,
and the outcome of obtaining the claimed compound was
reasonably predictable.”

60. In re Kubin
60
561 F.3d 1351 (Fed. Circ. 2009)
• Claims directed to polynucleotide (cDNA) encoding a particular
polypeptide (hNAIL protein)
– NK Cell Activation Inducing Ligand (NAIL)
– NK cells target and kill diseased cells and recruit other immune cells
– NAIL is a cell surface marker or receptor which modulates the activity
of NK cells.
• Exemplary Claim:
– An isolated nucleic acid molecule comprising a polynucleotide
encoding a polypeptide at least 80%
identical to amino acids 22-221 of SEQ ID NO:2,
wherein the polypeptide binds to CD48.
61. 61
In re Kubin
• Court recognizes dual nature of nucleic acids, moves them away from
treating nucleic acids solely under a chemical structural obviousness
analysis
• Court indicates that, given the factual circumstances, claimed invention
was “profoundly predictable” due to specific teachings in prior art and
advancements into cloning and sequencing technologies
• Subsequent decisions by Board of Patent Appeals & Interferences have
emphasized that “generalized” motivations to experiment in a given field
are not sufficient to meet the “obvious to try standard”
• Post-Kubin decisions from Board of Patent Appeals & Interferences also
emphasize absolute predictability not required to support obviousness
– Only a reasonable expectation of success is required
– Specific motivation/encouragement from prior art may become a surrogate for te
requisite “reasonable expectation of success”
62. 62
In re Kubin
• 2010 KSR Guidelines “teaching point”
“A claimed polynucleotide would have been obvious
over the known protein that it encodes where the skilled
artisan would have had a reasonable expectation of
success in deriving the claimed polynucleotide using
standard biochemical techniques, and the skilled artisan
would have had a reason to try to isolate the claimed
polynucleotide. KSR applies to all technologies, rather
than just the “predictable” arts”

72. Practice Tips for Preparing Application
72
• Continue to avoid unnecessary characterizations of the
invention by:
– Omitting background section
– Omitting recitation of objects of the invention and a summary
of the invention
• When unnecessary for utility purposes, do not
reference a particular problem faced by the inventor(s)
or solved by the inventor(s)
– Applications nationalized from
Europe should be scrutinized
for such references and the
references should be deleted
upon filing.
72
73. 73
Prima Facie Case of Obviousness
• If possible, assert that the examiner has failed
to establish a prima facie case of obviousness
– Always try to overcome rejection before rebutting
obviousness.
– For compounds, PTO must first establish structural
obviousness. Unexpected properties can then be
used to overcome rejection.
• Make sure that examiner has specified rationale
and set forth facts that support rationale.
• No hindsight reconstruction
74. 74
Guaranteed (almost) winners (still)
• Teaching away (but no stretching!)
• Modification renders prior art unsatisfactory
for intended purpose
• Modification changes the principle of
operation of a reference
• Combined references lack an element recited
in claim (unless common sense or ordinary
creativity fills in the gaps)
75. 75
Lack of Predictability (A-F)
• Except for the TSM test, all rationales (A-F)
relate to predictability.
– So argue the invention is not predictable!
– Argue no reasonable expectation of success
– Argue that elements work together in an
unexpected way.
76. 76
TSM
• If the TSM test is used, you can still argue that
there is no suggestion or motivation to combine
the prior art references or to make
modifications.
– Don’t assume that TSM rationale was used and do
not automatically frame response with typical
TSM arguments.
77. Assess PHOSITA 77
• If reasonable, and if it does not present any
complications for your positions with respect to 35
U.S.C. 112 ¶ 1, argue that the PHOSITA has a low level
of skill in the art and would not have been able to
combine the prior art references to reach the claimed
invention.
• When identifying the PHOSITA’s level of skill in the art,
remember that the skill of the actual inventor is not
necessarily relevant.
• Factors to be considered in identifying the level:
– Educational level of the inventor and others in the field
– Technology field of the invention
– Nature of the problems encountered in the field
– Previous solutions to the problem or related problems
77
78. General Prosecution Suggestions -78
Longer Shots
• Analyze prosecution history of prior art reference
to find “teaching away” or evidence of lack of
predictability
• Consider asserting that the prior art is
nonanalogous.
– While this approach is often very difficult, it should
not be overlooked.
• Secondary considerations
– Long-felt, unmet need; failure of others; etc.
79. Declarations 79
• Present a fact-based analysis of obviousness
• While declarations are still excellent fodder in
litigation, the facts established via declarations
are increasingly critical for overcoming
obviousness rejections and there may not be
another choice.
• So consider a declaration to address issues such
as “unexpected results”, “teaching away” and the
unpredictability of the combination to the skilled
artisan as these issues are questions of fact.
79
80. 80
Interviews
• Try to always interview the examiner
– Meet with the examiner in person
– If necessary, reach agreement on data to be
submitted in declaration that overcomes rejection
by showing unexpected results, lack of
predictability, secondary considerations,
problems in the art, level of skill, etc.
