4. What is Patent Application?
• A Patent Application is a request pending before
the patent office for the grant of a patent for
the invention described and claimed by that patent
application. The patent application consists of a
description of the invention (the patent specification) as
well as patent claims.
• However, patent claims define the scope and ambit of
the technology for which a patent is filed before the
patent office.
© www.techcorplegal.com “Where Technology, Business and Law
5. What is Patent Application?
• The term ”Patent Application” is also used to refer to the
process of applying for a patent, or to the patent
specification itself (i.e. the content of the invention
document filed with a view to initiate the process of
applying for a patent).
• You get protection for the claimed technology. Anything
outside the ambit is not covered. In other words, YOU
get protection for what you disclose.

9. Patent Title Define the Technology
• The title of the invention should be placed at the top of
the first page of the specification.
• The title of the invention should be meaningful.
• The title should clearly, concisely and as specifically as
possible indicate the subject to which the invention
relates.
• If the patent document contains patent claims in different
categories (product, process, apparatus, method,
use), this should be evident from the title.
© www.techcorplegal.com “Where Technology, Business and Law
10. Patent Title Define the Technology
• The word “patent,” personal names, fancy names, trade
names, trademarks or abbreviations or terms such as
“etc.” which do not serve to identify the invention or
technology should not be used in the title.
• The title should be brief but technically accurate and
descriptive and should contain fewer than 500
characters.
• For e.g. “ System & Method for …..” or “Apparatus
for…..”
© www.techcorplegal.com “Where Technology, Business and Law
11. Identifying Important Researchers / Inventors
for a technology domain
• In Patent law, an Inventor is the person, or persons who
contribute to the patent claims of a patentable invention.
In other words, people behind conducting the research.
• An inventor is the one with "intellectual domination" over
the inventive process.
• "Joint inventors", or "co-inventors", exist when a
patentable invention is the result of inventive work of
more than one inventor. Joint inventors exist even where
one inventor contributed a majority of the research work.
© www.techcorplegal.com “Where Technology, Business and Law
12. Identifying Important Assignees for a
technology domain
• The assignee is the business organization that has the
intellectual property right to the patent.
• The legal owner of the patent is designated as the
“Assignee” on United States Patents.
• When a company invest money in research and any
intellectual property which is generated during the
research work is owned by the company and
researchers assign the IP rights via signing an
assignment deed.
© www.techcorplegal.com “Where Technology, Business and Law
13. Identifying Important Assignees for a
technology domain
• In some cases, the inventor and the assignee may be
one and the same but an employee will more than likely
assign a patent to a company.
• Whatever inventions are made, they are immediately
transferred to the company upon conception.
• The company is said to be the 'assignee' and the
employee is the 'assignor'.
© www.techcorplegal.com “Where Technology, Business and Law
14. Identifying Important Assignees for a
technology domain
• The company is said to be the 'assignee' and the
employee is the 'assignor'.
• Many a times there is a clause in the employment
contract which clearly states that whatever intellectual
property originates during the tenure of the employment
would be owned by the company and the employee will
do the same by signing assignment deed.
© www.techcorplegal.com “Where Technology, Business and Law
15. US Patent Application Number
• A Patent Application Number includes a two digit
series code followed by a six digit serial number which is
assigned by the United States Patent And Trademark
Office (USPTO).
• Application numbers consisting of a series code and a
serial number are assigned by the Office of Patent
Application Processing (OPAP) immediately after mail
has been opened.
• If an application is filed using the Office’s electronic filing
system, EFS-Web provides an Acknowledgement
Receipt that contains a time and date stamp, an
application number and a confirmation number.
© www.techcorplegal.com “Where Technology, Business and Law
16. Patent Filing Date
• The filing date is the date when a patent application is
first filed at a patent office.
• The-filing date issued by the USPTO on a patent
application is of critical importance to an inventor or
patent owner because it determines who has priority
over the right to file a patent application for an invention.
© www.techcorplegal.com “Where Technology, Business and Law
17. Patent Filing Date
• The filing date is the date when a patent application is
first filed at a patent office.
• The filing date issued by the USPTO on a patent
application is of critical importance to an inventor or
patent owner because it determines who has priority
over the right to file a patent application for an invention.
© www.techcorplegal.com “Where Technology, Business and Law
18. Patent Filing Date
• For example, many European countries, and more
recently, the US, have first-to-file patent systems. This
means that the entity who was the first to file a patent
application for an invention is the only one whose patent
application will be allowed to go through the entire
process of examination for a possible issuance of a
patent. Thus, the system is essentially on a “first-come,
first-served” basis.
© www.techcorplegal.com “Where Technology, Business and Law
19. Understanding Importance of Patent
Classification Systems
• The Patent Classification is used to categorize and index
the technical details of the technology Patent
specifications.
• The classification assists a patent researcher to easily
identify patents in a particular domain of technology.
• The patent application when filed before any respective
patent office classifies the invention under predefined
technical classes and sub-classes by the patent
examiner.
© www.techcorplegal.com “Where Technology, Business and Law
20. IPC (International Patent Classification)
for Performing Patent Searches
• The International Patent Classification (IPC), established by
the Strasbourg Agreement, provides for a hierarchical system of
language independent symbols for the classification of patents and
utility models according to the different areas of technology to which
they pertain.
• The IPC divides technology into eight sections with
approximately 70,000 subdivisions. Each subdivision has a symbol
consisting of Arabic numerals and letters of the Latin alphabet.
IPC Class
US Class
© www.techcorplegal.com “Where Technology, Business and Law
21. USPC (United States Patent Classification) for
Coding different Technologies
• The USPC is a system for organizing all U.S. patent
documents and many other technical documents into
relatively small collections based on common subject matter.
• Each subject matter division in the USPC includes a major
component called a class and a minor component called a
subclass.
• A class generally delineates one technology from another
whereas Subclasses delineate processes, structural
features, and functional features of the subject matter
encompassed within the scope of a class.
• Every class has a unique alphanumeric identifier, as do most
subclasses.
© www.techcorplegal.com “Where Technology, Business and Law
22. Abstract Writing for a Technology
• The patent abstract includes a brief summary of the
disclosure as contained in the description, the claims,
and any drawings. It shall be as concise as the
disclosure permits.
• Abstract of Sample Food Invention -

23. Background of the Invention
• The background section of the patent application has to
show that there is a need in the art for the invention and
it also states about the earlier technologies being used.
• Any invention should solve an existing problem in the
technology domain.
• Prior patents filed in the same domain should be
mentioned.
24. Background of the Invention
Background of Sample Food Invention
Traditional energy sources are being depleted at a faster
rate than the new ones are being made. These are mainly
non-renewable resources and take millions of years to
form. Renewable energy sources are an alternative over
non-renewable ones and biomass is one of the way to
produce energy in affordable, clean and efficient way.
Biomass processing is an efficient way for exploitation of
biomass energy. Biogasification of waste materials rely
upon the anaerobic digestion or fermentation process.

science to which the invention or discovery appertains,
or with which it is most nearly connected, to make and
use the same.
© www.techcorplegal.com “Where Technology, Business and Law
28. Independent Patent Claims and
Dependent Patent Claims
• The patent claim or set of patent claims shall define the
matter for which protection is sought. Patent Claims are
the essence of a patent. Patent Claims shall be clear
and concise. They shall be fully supported by the
description.
• Independent Patent Claim(s) are written in such a way
that they can stand on their own.
© www.techcorplegal.com “Where Technology, Business and Law
29. Independent Patent Claims and
Dependent Patent Claims
• When the independent patent claims are drafted, they do
not refer to any other patent claim. An independent
patent claim contains a preamble and all of the elements
/ features necessary to define the invention /idea/
process/ method.
• A dependent patent claim, in contrast, only has meaning
when combined with a preceding patent claim which may
or may not be an independent patent claim.
© www.techcorplegal.com “Where Technology, Business and Law
30. Independent Patent Claims and
Dependent Patent Claims
• Writing patent claims is an art and not easy to learn. The
patent claim or set of patent claims define the matter for
which protection is sought. In other words, the scope of
the patent protection is defined by the claimed features
in the patent claims.
• The set of patent claims should be fully supported by the
description of the invention. BEST mode of performimg
should be disclosed.
© www.techcorplegal.com “Where Technology, Business and Law
