What is a patent?
A right to exclude others from making , using or selling what is claimed in the patent for the life of the patent.
It is NOT a right to make , use or sell your own invention.
Dr.krishnasarma Pathy
Why do patents have value?
Protection for a competitive advantage.
Barrier to entry for deterring competitors.
Licensing can generate revenue on product that are not important to the patent owner’s business.

Requirements for a patent
Novelty
Non Obviousness / Inventive Step
Utility (Usefulness / Industrial applicability)
Dr.krishnasarma Pathy
The “Novelty” Requirement
Novelty
• The invention was not known or used (region specific) by others prior to the date of filing of first application (EU & others) / date of invention (US).
• The invention was not patented or described in a printed publication any where prior to the date of filing of first application (EU & others) / date of invention (US).
Dr.krishnasarma Pathy
The Novelty Requirement (Cont)
Unpatentable for lack of Novelty• Product or process is expressly
described in a single prior art reference (Anticipation).
• Product or process is inherently present in a single prior art reference (Inherent anticipation).
Dr.krishnasarma Pathy
The ‘ Non obviousness ’ Requirement
An easy-to-use Non obviousness Analysis
• A different plus An advantage can Demonstrate Non obviousness
Dr.krishnasarma Pathy
The ‘ Non obviousness ’ Requirement (Cont)
The Claimed Invention A compound of the
structural formula
Where in R is a lower alkyl radical containing more than one and less than five carbon atoms.
The prior Art A journal publication
described a compound of the structural formula
Where in R is methyl

The ‘ Non obviousness ’ Requirement (Cont)
Analysis of the Non obviousness Issue
• The prior art compound required the R substituent to be methyl (one carbon atom); the claimed compounds required the R substituents to have two , three or four carbon atoms.
• Prior art compound had essentially no anti inflammatory properties; only the claimed compound possessed anti-inflammatory properties.
• The claimed compounds were not obvious in view of the prior art compound because their properties could not have been predicted by a person with ordinary skill in the art based on the structural differences.
• A compound and its properties are inseparable.Dr.krishnasarma Pathy
The ‘ Usefulness ’ Requirement
Usefulness
• Any practical utility• Utility must be expressly stated
Dr.krishnasarma Pathy
Patents are country specific
Almost every country has its own patent low and a person desiring a patent in a particular country must make an application for patent in that country , in accordance with that country’s requirements.
E.g. the rights granted under a United States patent extend only throughout the territory of the United States and have no effect in other countries.
Dr.krishnasarma Pathy
Who can obtain a Patent?
An inventor or any other person/company assigned by the inventor can obtain the patent over his invention.
Dr.krishnasarma Pathy
Details of Patent Specification
Title Field of the invention Background of the invention Summary Detailed description of the invention Claims Abstract Drawing
Dr.krishnasarma Pathy
What is a Patent claim?
A patent claim is a single sentence that clearly explain the “metes and bounds” of the invention.
Dr.krishnasarma Pathy
Metes & Bounds
A patent claim measures the boundaries of Intellectual property like a survey measures the boundaries of real property.
Dr.krishnasarma Pathy
Typical Patent Claims for Chemical Compound
A compound of the general formula I
A compound as claimed above which is N-[2-[[[5-(dimethylamino)methyl-2-furanyl]methyl]thio]ethyl]-N’-methyl-2-nitro-1,1-ethenediamine.

Claims
Independent Dependent Multiple dependent It is claims and not the patent
which are infringed.
Dr.krishnasarma Pathy
Claims (Cont.)
Claim 1.A method of testing the purity of a sample of lamotrigine or a pharmaceutical dosage form comprising lamotrigine , which method comprises assaying the said sample for the presence of N-[5-amino-6-(2,3-dichlorophenyl)-1,2,4-triazin-3-yl]-2,3-dichlorobenzamide. [Independent claim].
Claim 5.Asmaple of a compound as claimed in claim 1 which is in substantially pure from [dependent claim].
Claim 6.A sample according to claim 1 and 5 which has a purity level of 90% or above [Multiple dependent claim]. Dr.krishnasarma Pathy
Criteria for Naming Inventors in an Application
for Patent
All persons who contribute towards development
of patentable features of an invention should be named inventor(s).
All persons who have made intellectual contribution in achieving the final results of the
research work leading to a patent should be named inventor(s).
A person who has not contributed intellectually in the development of an invention is not entitled to be included as an inventor.
Dr.krishnasarma Pathy
Criteria for Naming Inventors in an Application
for Patent (Cont)
A person who provides ideas needed to produce the important features of the invention need not himself/herself carry out the experiments , construct the apparatus with his/her own hands or make the drawings himself/herself. The person may take the help of others. Such person who helped in conducting the experiments , constructing apparatus or making the drawing or models without providing any intellectual input are not entitled to be named inventors.
Dr.krishnasarma Pathy
Criteria for Naming Inventors in an Application for Patent
(Cont)
Quite often difficulties are experienced in deciding the names of inventors. To avoid such a situation, it is very essential that all scientists engaged in research should keep factual , clear and accurate records of daily work done by them in the form of diary/journals/note book. The pages in the diary should be consecutively numbered and the entries made be signed both by the scientist and the concerned leader.
Dr.krishnasarma Pathy
If two or more persons work together to make an invention to whom will
the patent be granted?
If each had a share in the ideas forming the invention as defined in the claims-even if only as to one claim, they are joint inventors and a patent will be issued to them jointly on the basis of a proper patent application. If, on the other hand , one of these persons has provided all of the ideas of the invention , and the other has only followed instructions in making it, the person who contributed the ideas is the sole inventor and the patent application and patent shall be in his/her name alone. Dr.krishnasarma Pathy
Time period to obtain patent
No fixed time and generally not predictable
However, the period of time which the patent office usually requires to review and grant the patent varies from about 1.5 to 3 years.

Dr.krishnasarma Pathy
Patent Filing
Provisional specification To be filed to protect the Intellectual
property and claim the earlier property dates.
Complete specification To be filed within 12 month from the
priority date if provisional application is filed. Dr.krishnasarma Pathy
Infringement and Validity of Patent
Dr.krishnasarma Pathy
Types of Infringement
Literal Infringement Infringement under doctrine of
equivalence Induced Infringement Contributory Infringement
Dr.krishnasarma Pathy
Literal Infringement
If patent claims methanol for crystallization and infringer uses methanol to crystallize , there is Literal Infringement of the patented invention.
Dr.krishnasarma Pathy
Infringement under doctrine of equivalence
If patent claims methanol for crystallization and infringer uses ethanol to crystallize , there is no literal infringement of the patented invention , however there is Infringement under doctrine of equivalence.
Dr.krishnasarma Pathy
Duty of patent Holder
It is the sole duty/responsibility of the patentee to see that his patent is not being infringed upon by someone else. It is the patentee’s duty to file a suit of infringement against the infringer.
Dr.krishnasarma Pathy
Invalidation/Opposition
Patents are not enforceable if obtained through inequitable conduct.
Patents can be challenged in court and invalidated.
One , all or different claims of patent can be subjected to invalidity challenges at one time.

India 2005
Understanding the present Scenario
Dr.krishnasarma Pathy
India in the WTO context
India is a signatory to the WTO resolution on TRIPS agreement.
India was thus committed to recognizing product patents by amending the Indian Patent Act , 1970.
Dr.krishnasarma Pathy
A Historical Perspective Indian patent act,
1970 In force since
20.4.72 A first step towards
recognizing intellectual property in India
Act only recognized process patents
This led to generic version of patented drugs , sold at very low prices
Indian companies have pushed up their market share since 1970 from under 30% to 72%.Growing at over 20% a year. Indian pharma sector is the third largest in the world in volume but much lower down in value of output because of the low prices.
Dr.krishnasarma Pathy
IPA (1970) Amended in March 1999
The patents (Second Amendment)
Amendment Bill 1999 Application for
product patents to be accepted
Application will be processed after 2005
Exclusive Marketing Rights for product
-Till grant of patent or
-For five years Exclusive marketing
right only for drugs for which patent application filed after 1 Jan 1995
Dr.krishnasarma Pathy
Patent Act 2005
Product patent allowed. Mere admixture not patentable. Mere discovery of new use not
patentable. Polymorphs and other forms like
enantiomers, salt, ester, combinations etc. not patentable unless significant enhancement in efficacy is shown.

Patent Cooperation Treaty (PCT)
Patent Cooperation Treaty (PCT)-1970(Amended in 1979 & 1984)
Dr.krishnasarma Pathy
PCT Application It is NOT a world patent. PCT offers a provision for
centralized process of patent filings. The application are designated as
WOXXXXXX. These application do not have any
exclusive rights to the Assignee/Applicant.

*It is not yet clear whether such provisions of extension would be granted in India in future.
** Allowable period during which applicants own publication / use/ presentation is not considered as prior art for his own patent application.
$ The term is calculated from date of filing of earliest application. For PCT application it is considered as date of filing of PCT application.
# For the application filed on or before 08-june-1995 the term is 17 year from publication or 20 years for earliest filing whichever is greater. For all application filed after 80-june-1995 the term is 20 years from date of earliest filing date.

Conclusion
Beginning today, do not overlook any potential patentable inventions that you create. A patent can be valuable intellectual property that can be used to exclude the competition or to generate financial returns.
