This document discusses different concepts of genes including:
1. Classical concepts viewed genes as units of heredity, transmission of characters, and mutation.
2. Molecular concepts define genes as the entire nucleic acid sequence required for protein synthesis, including coding and regulatory regions.
3. Genes have a fine structure and can be divided into functional units called cistrons based on complementation testing of mutants.
The document discusses several types and applications of polymerase chain reaction (PCR). It begins by explaining the basic three-step cycling process of PCR: denaturation, annealing of primers, and extension. It then describes several variations of PCR including inverse PCR, anchored PCR, asymmetric PCR, real-time PCR (RT-PCR), and PCR for site-directed mutagenesis. Inverse PCR is used to amplify unknown flanking genomic regions, while anchored and asymmetric PCR are used to generate single-stranded DNA products for downstream applications like sequencing. RT-PCR amplifies RNA sequences by first generating cDNA. PCR mutagenesis introduces mutations through altered primer sequences.
Ligase chain reaction (LCR) is a technique that can detect single base pair differences in DNA sequences. It uses a thermostable ligase and primers to exponentially amplify the target sequence if there is a perfect match. Mismatched sequences will not ligate and thus not amplify. LCR has been used to detect genetic diseases, bacteria, viruses, and other sequences. Molecular probes are labeled DNA or RNA fragments that can identify complementary sequences. They are often labeled with radioactive isotopes or non-radioactive molecules like biotin or digoxigenin for detection. Molecular probes have applications in research, diagnostics, and forensics.

Chromosome walking involves isolating overlapping DNA fragments in steps to characterize large chromosome regions. Chromosome jumping uses rare cutting enzymes to isolate larger DNA fragments spanning hundreds of kb. Transposon tagging involves inducing transposon insertion mutations, identifying the disrupted gene, and using the transposon as a tag to clone the gene. Map-based cloning localizes a gene of interest by identifying closely linked markers, screening libraries to find flanking markers, and identifying the gene between markers through complementation tests.
Genomic and cDNA libraries are constructed to isolate genes of interest from organisms. Genomic libraries contain total chromosomal DNA while cDNA libraries contain mRNA from specific cell types. DNA is digested and ligated into vectors to clone fragments. Libraries are screened using probes and PCR to identify clones containing genes of interest. cDNA libraries are useful for studying eukaryotic gene expression as they contain mRNA from specific cells. Thousands of clones may need to be screened to have high probability of isolating a particular gene fragment.
There are three main methods for isolating genes:
1. Using an automated gene machine to synthesize genes from predetermined nucleotide sequences.
2. Gene cloning, which involves inserting a DNA fragment into a vector that is then transferred into a host cell to produce multiple copies.
3. Polymerase chain reaction (PCR), which amplifies a specific DNA sequence using primers that flank the target sequence.
The document discusses techniques for DNA sequencing, including early methods developed in the 1970s by Maxam and Gilbert as well as Sanger. It provides details on how both methods work, such as using specific chemical or enzymatic reactions to generate labeled DNA fragments of different lengths corresponding to nucleotide positions in the sequence. The document also describes how these methods were later automated, using fluorescent tags on dideoxynucleotides and capillary electrophoresis to simultaneously sequence multiple samples in a single gel. This allowed rapid determination of thousands of nucleotides and enabled large genome sequencing projects such as the Human Genome Project.
This document discusses gene synthesis techniques and blotting methods. It provides details on:
1) The first chemical synthesis of genes in the 1970s, including a gene for yeast tRNA and bacterial tRNA.
2) Methods for artificially synthesizing genes using oligonucleotides and ligating DNA fragments.
3) Techniques for analyzing DNA, RNA, and proteins - Southern blotting detects DNA, Northern blotting detects RNA, and Western blotting detects proteins.
This document discusses different types of vectors that can be used for genetic engineering, including animal viruses, plant viruses, retroviruses, shuttle vectors, and binary vectors. It provides details on the structure and use of tobacco mosaic virus (TMV) as a plant viral vector, describing how foreign genes can be stably replicated and spread systemically in plants using this system. It also summarizes key features of yeast episomal plasmids (YEps), retroviral vectors based on murine leukemia virus, and the binary vector system used for plant transformation via Agrobacterium tumefaciens.
The document summarizes phagemid and bacterial artificial chromosome (BAC) vectors. It describes that phagemid vectors are plasmids that contain both plasmid and phage origins of replication. Specifically, it discusses the features of pBluescript II phagemid vectors, including their polylinker and RNA polymerase promoter sequences. It also describes how pBluescript II phagemid vectors can produce blue or white colonies depending on insert presence. The document then explains that BAC vectors are low-copy plasmids that can hold up to 300kb DNA fragments. Examples of BAC vectors like pBAC108L and pBeloBAC11 are provided, with details about their replication origin and partitioning functions.
This document discusses P1 vectors, which are cloning vectors derived from the P1 bacteriophage. P1 can transfer DNA between bacterial cells through transduction. The document describes:
1) The construction of P1 vectors pNS358 and pNS582, which contain P1 packaging and replication elements to clone and propagate large DNA fragments.
2) How the P1 system was used to clone DNA fragments up to 100 kb by packaging ligated vector/insert concatemers into phage heads.
3) Applications of P1 vectors including the creation of P1-derived artificial chromosomes (PACs) which can accommodate relatively large DNA fragments for cloning and mapping genomes.
Cloning and Expression Vectors document discusses:
1) Cloning a gene of interest involves inserting it into a vector that can be replicated in host cells, producing recombinant DNA molecules.
2) Vectors contain features like replication origins, antibiotic resistance genes, and unique restriction sites to facilitate cloning and isolation.
3) Early cloning experiments demonstrated that recombinant plasmids containing both prokaryotic and eukaryotic DNA could replicate stably in bacteria, allowing genetic engineering.
- Baculovirus expression vectors allow genes of interest to be expressed in insect cells. The gene is inserted into the baculovirus genome, downstream of the strong polyhedrin promoter.
- When the recombinant baculovirus infects insect cells, the gene is highly expressed. This system is useful for producing recombinant proteins.
- T7 expression systems also allow high level expression of genes in bacteria. The gene of interest is placed in a plasmid downstream of the T7 promoter. This plasmid is introduced into E. coli containing the T7 RNA polymerase gene, which is induced to express the polymerase.
Molecular mechanism of suppression, somatic mutationsPromila Sheoran
Somatic mutations occur in body cells rather than germ cells and are therefore not inherited. If a somatic mutation happens in a developing or dividing cell, it can result in a clone of mutant cells. This may appear as a mutant sector or patch of cells. Somatic mutations have little effect on phenotype in post-mitotic cells. However, cancer-causing mutations can disrupt cell division control and cause uncontrolled growth of a tumor. While somatic mutations themselves are not passed to offspring, plants can propagate clonally from somatic tissue, indirectly transmitting the mutation.
Spontaneous mutations arise from errors in DNA replication and spontaneous DNA damage. Errors in replication can result in base substitutions if an incorrect base pairs with another. Spontaneous DNA damage includes depurination, in which bases are lost from DNA, and deamination of cytosine to uracil. Large deletions and duplications can also occur spontaneously. These replication errors and lesions generate the genetic variation that allows organisms to evolve in response to environmental changes. Spontaneous mutations are the ultimate source of natural genetic variation seen within populations and are responsible for certain human genetic diseases when they disrupt important genes.
This document discusses various chemical and physical mutagens and their mechanisms of inducing mutations. It describes how chemical mutagens like base analogues (5-bromouracil and 5-fluorouracil) can incorporate into DNA and pair with the wrong bases, disturbing replication. Methylating agents and acridine dyes can respectively add methyl groups or insert themselves into DNA, changing the genetic code. Deamination agents can remove functional groups from bases, altering base pairing. Physical mutagens like radiation and temperature changes can also distort or break DNA, inducing mutations.

Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid

Anti-Universe And Emergent Gravity and the Dark UniverseSérgio Sacani
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.
Embracing Deep Variability For Reproducibility and Replicability
Abstract: Reproducibility (aka determinism in some cases) constitutes a fundamental aspect in various fields of computer science, such as floating-point computations in numerical analysis and simulation, concurrency models in parallelism, reproducible builds for third parties integration and packaging, and containerization for execution environments. These concepts, while pervasive across diverse concerns, often exhibit intricate inter-dependencies, making it challenging to achieve a comprehensive understanding. In this short and vision paper we delve into the application of software engineering techniques, specifically variability management, to systematically identify and explicit points of variability that may give rise to reproducibility issues (eg language, libraries, compiler, virtual machine, OS, environment variables, etc). The primary objectives are: i) gaining insights into the variability layers and their possible interactions, ii) capturing and documenting configurations for the sake of reproducibility, and iii) exploring diverse configurations to replicate, and hence validate and ensure the robustness of results. By adopting these methodologies, we aim to address the complexities associated with reproducibility and replicability in modern software systems and environments, facilitating a more comprehensive and nuanced perspective on these critical aspects.

5. Some Global Opportunities and Challenges with
Potential BioBusiness Implications
• Globalization - and the rapidly growing global economy (and growing inequity between
“haves” and “have nots”)
• Healthcare and Biomedical Sciences - Advances in healthcare and the biomedical
sciences, the genomics revolution and the move toward personalized medicine (and
the need to manage the cost of healthcare as populations age)
• Feeding the World – increased interest in more nutritious and less chemically tainted
foods (and the need to feed more people in the face of ever diminishing arable land)
• Renewables and Sustainability - Increasing demand for renewables and more
sustainable production technologies – biofuels, new biomaterials (and solving the
problems of global warming, environmental contamination and waste management)
• Responding to Threats – responding to natural and human generated threats to
economic development and stability (from pandemics, to natural disasters, to concerns
about bioterrorism)
6. The BioBusiness Innovation Landscape
Recommended Approach:
Focus on “Summit” opportunities – putting people,
technologies and resources together to capture the value
proposition
Summit Opportunities: Technology and knowledge intensive, few
competitors, high barriers to entry; high margins with well-
developed business case, “new” economy principles apply. High
BioEnterprise interest

Critical Success Factors (given good infrastructure, facilities,
policies, etc):
Smart People
Smart Ideas
Smart Money (immaterial if public or private sector driven:
Silicon Valley model – driven by private money; European model
– driven by public money)
Smart Alliances and Partnerships (throughout the world)
8. Understanding Innovation…
It is pretty simple:
You do some stuff. Most fails. Some works.
You do more of what works.
If it works big, others quickly copy it. Then you do something else.
The trick is the doing something else.

– Decontaminate lab bench before and after work
40. General Operational Practices
• Proper attire
– Minimum – lab coat, safety glasses, gloves
• Plan your work
– Know in advance what you are working with
– Read available resources (MSDS)
41. Biotechnology for developing countries
The challenge according to FAO
• To feed a population of 9 billion persons by 2050,
without allowing for additional imports of food,
continents have to increase their food production
roughly:
– Africa 300%
– Latin America 80%
– Asia 70%
– Even the US has to increase food production by 30% just
to supply food for the projected population of 348 million
person
42. “New” constraints
• Erosion, water and irrigation problems
• Climate change => Global warming?
• Soil fertility
• Urbanization and land being retired from production
• Consumer concerns about intensive agriculture: Organic,
Fair Trade
• Competition from biofuels production
• Social, philosophical, ethical and religious concerns over
the food production system
• Concerns over globalization and corporate control of
agriculture
• …
43. The Green Revolution
• Transformation of agriculture during 1940s-1970s that
lead to significant increases in yields
• Firmly based on:
– Agricultural production needs to keep pace with
population growth
– Agricultural sciences philosophy of maximizing
production per unit of land
– Plant breeding developments of the late 19th early 20th
centuries
• Initially focused on a few crops (Wheat, rice, maize) but
has been expanded
44. Norman Bourlag: Father of the Green
Revolution
• Developed the wheat program that later became CIMMYT in 1963
– Shuttle breeding
– Incorporate short-stature genes into wheat
– Increased yield and rust resistance in wheat
• Mexico:
– 1948 self sufficient wheat producer
– 1965 Net exporter
• Won Nobel Peace Prize in 1970 and World Food
Prize
• Genesis of the Consultative Group of International
Agricultural Research ( CGIAR)
45. How was the Green Revolution possible? An
agronomist perspective on a technological
triumph as an engineering feat…
• Incorporation of a dwarfing genes from natural populations into
wheat and rice
• In maize: more vertical orientation of leaves, reduces self-shading
while allowing planting of narrower rows and thus increases in
densities
• Plants bred to dedicate a larger share of photosynthesis efforts to
grain rather than to stems and leaves
– Harvest index of older varieties was 20% whereas HYV around 50-
55%
• Relatively insensitive to day length – can be planted in a
wider range of latitudes
• Increased responsiveness to fertilizer and water
46. Green Revolution: Successes
• Significant increases in yields and production
– From 1950 to 1992, the world’s grain output rose from 692
million tons produced on 1.70 billion acres of cropland to 1.9
billion tons on 1.73 billion acres
– India: food production increased from 50 to 205 million tons
during the last 5 decades
– But, barely happened in Sub-Saharan Africa
• Economic output per hectare increases significantly
• 30% increase in cereal and calorie availability per person
• Poverty reductions—some studies show this is attributed to GR
raising farmers incomes
47. Green Revolution: Social and Economic Criticisms
• Does not address underlying social, cultural, ethnical and
institutional constraints that create vulnerability and thus affect
livelihoods
– Is hunger and food insecurity a question of production or unequal
distribution of resources?
• Increased mechanization affected rural labor employment
• Debt effects and credit institutions necessary
• Technology not scale neutral
– Uneven adoption as larger/wealthier farmers adopted first capturing
larger share of benefits
• Landowner/Landholder displacement
• Dependence on pesticides and fertilizers
48. Green Revolution: Environmental/Ecological
Criticisms
• Loss of agricultural biodiversity, not so clear effect on wild
biodiversity
– Focus on few crops => monocultures
• Increased uses of pesticides and the pesticide treadmill
• Increased use of fertilizers
• Irrigation
– Negative impacts of salinization, damage to soils, and
lowering of water tables
– Need to build dams and irrigation systems
49. Biotechnology as a tool
What is biotechnology?
• Manipulation of living organisms for a useful purpose
• Definition that covers a broad range of techniques
– Traditional: Plant breeding, tissue culture, micropropagation
– Modern: Marker assisted selection, Genetic Modifications
and Genomics
• Only GM products are currently regulated for
biosafety
52. Implications for developing country agriculture
• Majority expansion is in four crops and two traits (insect
protection and herbicide tolerance) produced by industrialized
countries for its agriculture
• Diffusion to developing has been a (fortunate) development
• Challenge now is meeting explicit needs of
– Developing countries
– Smallholder / resource poor farmers
– Crop / traits
53. R&D and innovation for and by developing
countries
• Crops and traits of interest/value have been produced
• Capacity to develop GM crops and other biotechnologies
– Advanced => China, Brazil, Mexico, India, Argentina
– Medium- Advanced => Philippines, Thailand, Indonesia
• Next Harvest documented 270 technologies in 16
developing countries
54. Why GM biotech?
• Embodied technologies
• Address specific productivity constraints not easily
addressed by conventional means
• Can be deployed in low resource use production systems
• Flexible – fit with other production systems
– GM and Integrated Pest Management
– GM and organic production methods (!!!)
• Impacts can be non-pecuniary, indirect, and scale neutral
• Scalable
55. How does a producer benefit? Insect resistance
traits
The case of Bt cotton
56. Bt maize in the Philippines
• Growing Bt maize significantly increases profits and yields
• Significant insecticide use reductions
• Adopters tend to be
– Cultivate larger areas
– Use hired labor
– More educated
– have more positive perceptions of current and future status
57. Bt maize in Honduras
•Excellent target pest control
•Bt yield advantage 893-1136 Kg ha -1 yield (24-33%)
•Bt maize yields preferred even by risk averse producers
•100% higher seed cost than conventional hybrid
•Institutional issues important
58. Black Sigatoka Resistant Bananas in
Uganda
•Consider irreversible and reversible cost and benefits
by using the Real Option model
•One year delay, forego potential annual (social)
benefits of +/- US$200 million
•A GM banana with tangible benefits to consumers
increases their acceptance for 58% of the population
59. Productivity: Evidence for Bt Cotton Gains
Bt cotton in:
• United States: yield effect 0 – 15%
• China: yield effect 10%
• South Africa: yield effect 20%-40%
• India: yield effect 60 – 80 %
In every country have reduction in chemical usage
60. The Impact of Bt Cotton in India
• Bt cotton is used to provide resistance to the American
bollworm (Helicoverpa armigera).
• The technology was developed by Monsanto and was
introduced in collaboration with the Maharashtra Hybrid
Seed Company (Mahyco).
• Field trials with these Bt hybrids have been carried out since
1997 and, for the 2002/03 growing season, the technology
was commercially approved by the Indian authorities.
61. Results
• Bt hybrids were sprayed three times less often against
bollworms than the conventional hybrids.
• On average, insecticide amounts on Bt cotton plots were
reduced by almost 70%, which is consistent with studies from
other countries.
• At average pesticide amounts of 1.6 kg/ha (active ingredients)
on the conventional trial plots, crop damage in 2001/02 was
about 60%. Bt does not completely eliminate pest-related yield
losses.
62. Results II
• Average yields of Bt hybrids exceeded those of non-Bt
counterparts and local checks by 80% and 87%, respectively.
• 2001/02 was a season with high bollworm pressure in India,
so that average yield effects will be somewhat lower in years
with less pest problems.
63. Concluding comments
• Biotechnology and Genetically Modified Crops are still only
technologies
• Similarities and differences with other technologies
• Actual and potential benefits from GM technology
adoption…important tool to consider. Cannot disregard
• Developments in the public sector in developing countries
• Additional crops/traits of interest whose limitations can
probably be only addressed through biotechnology means,
will be available if we manage to resolve institutional and
regulatory issues.
64. Intellectual Property Rights
•Patents
•Industrial designs
•Trade and service marks
•Copy rights
•Geographical indications or appellations of origins
•Layout designs (of integrated circuits).
•Neighbouring rights.
•Undisclosed INFORMATIONS (trade secrets).
•Anticompetitive practices in contractual licenses.

67. Major cases of IPR in Biotechnology
1. The IP situation with golden rice
2. Diamond v. Chakrabarty Patent Infringement
3. India-US Basmati Rice Dispute
4. Novartis patent case: cancer drug Glivec
68. 1.The IP situation with golden rice
• ~70 patents and patent applications might be applicable to
golden rice when all patents issued in or applied for in all
countries were considered.
•A dozen material transfer agreements were also identified, 1 of
which needed a license.
•The published analysis, and legal opinion, concluded that, in
practice, only a few patents were applicable in developing
countries.
69. Resolving the IP constraints with golden rice
1. Assembly of IP and tangible property rights:
- within a few months, in licensing, for humanitarian use,
led by Zeneca (Adrian Dubock), of key IP components
(Bayer AG, Monsanto, Novartis AG, Orynova BV, Zeneca
Mogen BV, others)
2. Out-licensing, by Syngenta, via the inventors, the bundled IP to
public sector institutions in developing countries:
- Bangladesh India, Indonesia, Philippines, Vietnam and
many more
- Policy support from Syngenta’s chairman, Heinz Imhof
70. Principal terms of the humanitarian license
• For use by resource-poor farmers
(< US$10,000/year from farming)
• Use of public varieties
• No technology fee
• Farmers are allowed to reuse harvested seeds
• No release in countries lacking biosafety regulations
• Export to licensees for research and use is permitted
• Improvements:
– Humanitarian use allowed (Syngenta already licensed many
improvements)
– Commercial rights to improvements are granted back to
Syngenta
71. 2. Diamond v. Chakrabarty Patent Infringement
The case was heard in the United Sates Supreme Court in
1980.
It entailed the patentability of genetically modified
organisms.
Genetic engineer ,Ananda Mohan Chakrabarty developed a
bacterium called Pseudomonas putida.
This was while working with General Electric.
The bacterium can break down crude oil which made it
suitable for treating future oil spills.
72. Chakrabarty
• He was an investor of the bacterium by the General Electric.
• This was when the company applied for patent.
• The patent examiner rejected the application.
• This was because living things were not being patentable
subject matters at the time.
• The examiner quoted Section 101 of the Title 35 U.S.C.
73. Case
Board of Patent Appeals and Interferences upheld its
initial decision.
The United States Court of Customs and patent did not.
It overturned this case in favor of Chakrabarty.
Aegued that all micro-organisms are living things does not
have legal significance.
Sidney A. Diamond who was the Patents and Trademarks’
commissioner made an appeal to Supreme Court.
This case was deliberated on 17th March 1980.
74. Court’s Decision
A decision was made on 16th June 1980 and on 31st March
1981.
This was USPTO granted patent which was to Chakrabarty’s
favor.
The court noted that a live micro-organism made by human
under Title 35 U.S.C, 101.
The micro-organism of the respondent constituted of a
composition of matter.
The decision was written by Warren E. Burger, the Chief
Justice.
Others who joined him were Potter Stewart, William
Rehnquist, John Paul Stevens and Harry Blackmun.
75. 3. Basmati Rice and Asia
• Rice is an important aspect of life in the Southeast and other parts
of Asia.
• For centuries, it has been the cornerstone of their food and
culture.
• Basmati has been grown in the foothills of the Himalayas for
thousands of years.
• Basmati rice is being grown in subcontinent for centuries.
• Its flavour and aroma has been developed through selective
breeding for thousands of years.
• It is common knowledge that what Champagne is to France,
Basmati is to subcontinent (Pakistan and India).
76. Basmati Rice
• Basmati means the “queen of fragrance or the perfumed
one”.
• Origin: Pakistan and India
• Indian varieties are Safidon, Haryana, Kasturi (Baran,
Rajasthan), Basmati 198, Basmati 217, Basmati 370,
Kasturi, Mahi Suganda.
• Pakistani varieties Basmati 370, Super Basmati, Pak
(Kernal) Basmati, Basmati 386, Basmati 385 and Basmati
198.
77. The Case Issue
In the late 1997, when an American company RiceTec Inc. was granted a
patent by the US patent office to call the aromatic rice grown outside India
"Basmati", India objected to it. India has been one of the major exporters of
Basmati to several countries and such a grant by the US patent office was
likely to affect its trade. Since Basmati rice is traditionally grown in India and
Pakistan, it was opined that granting patent to RiceTec violated the
Geographical Indications Act under the TRIPS agreement. A geographical
indication (sometimes abbreviated to GI) is a name or sign used on certain
products which corresponds to a specific geographical location or origin (e.g..
a town, region, or country). The use of a GI may act as a certification that the
product possesses certain qualities, or enjoys a certain reputation, due to its
geographical origin. RiceTec's usage of the name Basmati for rice which was
derived from Indian rice but not grown in India, and hence not of the same
quality as Basmati, would have lead to the violation of the concept of GI and
would have been a deception to the consumers.
78. Patent Advantage to RiceTech
• RiceTec able to not only call its aromatic rice Basmati within
the US, but also label it Basmati for its exports.
• Captures the whole US trade market.
• Exclusive use of the term “basmati”.
• Monopoly on breeding 22 farmer-bred Pakistani basmati
varieties with any other varieties in the Western Hemisphere.
• Proprietary rights on the seeds and grains from any crosses.
79. Disadvantage of Patent to India and Pakistan
• Economic loses.
• Global trade losses.
• Both countries lose their global market share.
80. Government of India Response to Patent
• Government of India under severe pressure from its exporters
and farmers logged an appeal with USPTO.
• They submitted the evidence to USPTO.
• India exports about 400,000 - 500,000 metric tons of Basmati
annually. In 1996-97, India exported approximately 523,000
tonnes of Basmati to Europe.
81. Result of patent case
• RiceTec Inc. took back 15 claims out of 20
• They also took back its claim on the name
“Basmati”.
82. 4. Novartis patent case
•Glivec is a medicine discovered and developed by Novartis for
the treatment of chronic myeloid leukemia (CML), a cancer of
white blood cells and for the treatment of a rare form of stomach
cancer called gastrointestinal stromal tumor (GIST).
•Glivec is one of the first cancer drugs that validate rational drug
design, based on an understanding of how some cancer cells
function. These molecularly targeted drugs are different because
they target abnormal proteins that are fundamental to the cancer
itself.
83. •Glivec, used in treating chronic myeloid leukemia and some
other cancers, costs a patient about $2,600 (Rs 1,30,000) a
month. Its generic version was available in India for around
$175 (Rs 8,750) per month, reported Associated Press. The
medicine is the lifeline for poor in many developing countries.
•Novartis had argued that it needed to new patent to protect
its investment in the cancer drug Glivec while activists said the
company was trying to use loopholes to make more money out
of a drug whose patent had expired.
84. •Glivec has been patented in nearly 40 countries but only faced
problems in India. The drug was given an EMR by the Indian
patent office in the year 2003, which was for the duration of 5
years. Later, Novartis sued Ranbaxy and Cipla before the High
Courts of Madras and Bombay for making the generic versions
of Glivec. Novartis has fought a legal battle in India since 2006
for a fresh patent.
•In a landmark judgement, India's Supreme Court on December
2014, rejected a patent plea by Swiss drugmaker Novartis AG
for cancer drug Glivec, boosting the case for cheaper drugs for
life-threatening diseases.
