In this month's podcast episode, we’re talking about claims – the fundamental building blocks of a patent. There simply is not a more important concept to grasp in all of patenting. As a former chief justice of the Federal Circuit once famously said, “The name of the game is the claim.” And in terms of what game you’re playing, the claims are where you separate the patents playing checkers from the patents playing chess. This is where your patent practitioner earns their money and as you’ll learn today, also where the mostly costly mistakes can be born. As David Cohen, a Patently Strategic regular, has said in the past, "Ninety percent of the mental exercise in drafting patents is in the strategy of looking around corners, anticipating the future, and trying to capture as many would-be infringers as possible.” How your claims are crafted is literally the difference between a patent being an intellectual asset and a worthless stack of paper. ​ In this month’s episode, Ty Davis, Patent Strategy Associate here at Aurora, leads a discussion, along with our all star patent panel, delving deeply into: ⦿ Claim fundamentals ⦿ Claim drafting strategies ⦿ How to think about claims in the context of infringement ⦿ And in the game of patenting, how to move like a queen, so you’re not treated like a pawn. Ty is joined by our always exceptional group of IP experts, including: ⦿ Dr. Ashley Sloat, President and Director of Patent Strategy at Aurora ⦿ Kristen Hansen, Patent Strategist at Aurora ⦿ Dr. David Jackrel, President of Jackrel Consulting ⦿ Marie Smyth, Patent Agent, formerly with Greenberg Traurig and Meta ⦿ Porter Thames, J.D. and Patent Agent at SMU Science and Technology Law Review ** Mossoff Minute ** This month's Mossoff Minute, featuring Professor Adam Mossoff, looks at the poorly named Advancing America's Interests Act and its potential impact on the ITC being able to block import of products that infringe on American patents.

2. Ice Breaker
• What is the pictured invention?
• Problem Statement: In
apartments, children and babies
do not sufficient access to fresh
air.

3. Ice Breaker-
Continued
• That’s right... A baby cage for
apartment windows.
• The cages became popular in
London in the 1930s among
apartment dwellers without
access to backyards.
• .

4. Shared Problem Solving
• Fun Strategy Tidbits?
• Any problems you are encountering
with the USPTO?
• Any practice issues arising?
• Any technical issues you are facing?

5. Claim Strategies - Overview
•What Are Claims?
•How to Claim
•Claim Transitions
•Claim Strategy
•Infringers/Infringement
•Example Case Studies
•Takeaway

6. Claims
“The name of the game is the claim.” Giles Rich (Chief Judge of the
Federal Circuit 1982-1999)
• Claims are often referred to as the metes and bounds of a patent
• Claims define the subject-matter that is protected by the patent or
sought to be protected by the patent application

7. What Can be Claimed? (Utility)
• Machine
• Example: A new and useful paving machine
• Process
• Example: A new and useful method of paving
• Method of Treatment
• Article of Manufacture
• Example: A new and useful shovel for paving
• Composition of Matter
• Example: A new and useful pavement composition
• OR any new and useful improvement thereof

8. Claim Transitions
• Comprising
• Most common
• Can be combined with any element known in the art and motivation for
a phosita to combine
• Consisting of
• Limited to only elements recited
• Infers that the invention is only as described
• May be chemical, pharmaceutical, biotech, or in art that is unpredictable
• Consisting essentially of
• Intermediate between comprising and consisting of
• May include elements which do not materially affect the invention

9. Method of Treatment Claims
• Typically take the form of: A method of treating [medical condition X]
which comprises administering to a subject an effective amount of
[compound Y]
• Can be patentable in USA, Australia, and Russia
• Many countries, including, Canada, China, Israel, Japan, South Korea
and Taiwan do not allow the patenting of method of treatment

10. How to claim?
• Clear: shouldn’t allow for speculation
• Supported: should be supported in the description and drawings
• Complete: should cover the invention adequately
• AND don’t forget that you are trying to capture the idea…. Not the
design!!!

11. How to claim? (continued)
• Independent claims
• Standalone
• Includes the minimum limitations for the invention
• Dependent claims
• Adds limitation(s) to the independent and any previous dependent claim
• May define alternative embodiments
• Add non-essential limitations
• Adds breadth to the independent claim

12. Claim Strategies
• What is the invention?
• What is the prior art?
• What is the company? Selling a product, a service, product and a service,
and/or attempting to monetize the patent?
• Who are the competitors?
• Who is the infringer?
35 USC 271(a)- Except as otherwise provided in this title, whoever without authority makes,
uses, offers to sell, or sells any patented invention, within the United States or imports into
the United States any patented invention during the term of the patent therefor, infringes the
patent.

13. Infringers
• Who might be the infringer? Where are they?
• Can you identify them? Can you spot the infringement?
• Is the infringement direct or indirect?
• How do we make sure the infringement is done by one entity?

14. Divided Infringement
• Divided infringement occurs when more than one actor collectively performs
all the steps of a method claim, or use disparate elements of a system claim
such that no one party directly infringes a patent under § 271(a).
• A recent Federal circuit ruling established a more expansive test for divided
infringement: divided infringement has not occurred (1) where the first party
directs or controls the actions of the other party; and (2) where the first party
and the other party form a joint enterprise (a principal-agent relationship, a
contract, etc.).

15. Divided Infringement: Example
• Tropp v. Travel Sentry, Inc
• A method of improving airline luggage inspection by a luggage screening entity,
comprising: (1) providing a luggage lock with an identifier that can be unlocked
by a master key, (2) marketing the lock to emphasize that it is subject to a
special screening procedure, (3) the identifier signaling to a luggage screener
that the lock can be opened with the master key, and (4) the luggage screener
using the master key to open the luggage

16. Infringement case part 1/5
• Syngenta Crop Prot., LLC (SCP) v. Willowood, LLC (WW)
• SCP asserted four patents directed to a fungicide compound and its
manufacturing process

17. Infringement case part 2/5
• Syngenta asserted four patents to which it is assignee
• ‘076 and ‘256 patent-
• Composition patent for compounds including azoxystrobin
• ‘138 patent-
• Method patent
• Two step process-
• An etherification step to form an intermediate compound then used in a condensation step to
produce azoxystrobin
• ‘761 patent-
• Method patent
• Processes for the preparation of Azoxystrobin using DABCO [diazabicyclooctane] as a
Catalyst and Novel Intermediate Used in the Process
• Requires at least “the presence of between 0.1 and 2 mol% of DABCO”

18. Infringement case part 3/5
• ‘076 and ‘256 patent-
• Composition patent for compounds including azoxystrobin
• Found to be directly and inducedly infringed by WW USA but not by WW China

19. Infringement case part 4/5
• ‘138 patent-
• Method patent
• Two step process-
• An etherification step to form an intermediate compound then used in a condensation step to
produce azoxystrobin
• Were not found to be infringed due to divided infringement… but was later reversed by the
Federal Circuit, directly citing 35 USC 271(g)

20. Infringement case part 5/5
• ‘761 patent-
• Method patent
• Processes for the preparation of Azoxystrobin using DABCO [diazabicyclooctane] as a
Catalyst and Novel Intermediate Used in the Process
• Requires at least “the presence of between 0.1 and 2 mol% of DABCO”
• Was found to be infringed

21. Takeaway as a Practitioner
• As a practitioner, claim drafting is paramount and is one of the first steps of
drafting an application.
• Ensures that the practitioner and the client are on the same page with what is being invented
• Allows the practitioner an opportunity to brainstorm strategy with the client
• Ensures that appropriate support will be formed by the specification and the figures

22. Summary Quote
• "Ninety percent of the mental exercise in drafting patents is in the strategy
of looking around corners, anticipating the future, and trying to capture as
many would-be infringers as possible.”
• - David Coen
