46. What are the rights of a patent owner?
1. What is a patent?
A patent is a grant of the exclusive rights to an
inventor; specifically the right, within the U.S. to exclude others
from making, using, selling or importing the invention. A patent
is considered personal property, and may be assigned or licensed
by the owner
2. What are the different types of patents?
Utility patents are patents granted for any new, useful
and non-obvious machine, material or process. Design patents are
patents granted for any new and non-obvious design of an article
of manufacture. In addition, the Patent Office issues plant patents
on new varieties of asexually reproduced plants.
3. What is the term of a patent?
Utility Patents are normally valid for 20 years from
the priority filing date –usually the original filing date
– of a patent application. Design Patents are valid for a
term of only 14 years. A patent term can be extended if the examination
period exceeds a prescribed period of time.
4. What happens when the term of a patent
expires?
When a patent on an invention expires or goes abandoned, the invention
enters the public domain. The invention can then commercially exploited
by others.
5. How do patents, trademarks and copyrights
differ?
• A Patent is the grant of a
limited monopoly to an inventor, to exclude others from making,
using, selling or importing a patented invention or design
• A Trademark is a word, name, symbol or device which indicates
the identity of the source of a product or service. A trademark
prevents others from using a confusingly similar mark to market
the same products or services.
• A Copyright is a bundle of rights regarding a creative work
fixed in a tangible medium, such as a sound recording, text or film.
A copyright grants the ‘owner’, the exclusive right
to reproduce, copy, perform, display or prepare derivative works
of the copyrighted work. Copyright registrations are issued by the
U.S. Copyright Office rather than the Patent and Trademark Office.
6. Who can apply for a patent?
Only an inventor or inventors can apply for a patent.
In order to obtain a patent, all co-inventors must submit oaths
or declarations. If an inventor dies or becomes incapacitated after
conceiving of an invention and reducing it to practice, the legal
representative of the inventor can file the patent application on
the inventor’s behalf.
If the inventor works for a company, only the inventor (employee)
may apply for the patent. The Patent Office does not adjudicate
questions of ownership of inventions under a work for hire, however
the Patent Office will accept for recordation assignments of patent
rights. If a person obtains a patent under false pretenses, the
patent is invalid. Moreover, the applicant can be subjected to criminal
prosecution.
7. What can be patented?
Any new, useful and non-obvious process, machine, material or composition
of matter; or an improvement to any of these, can be the subject
of a utility patent. Any new and non-obvious ornamental characteristic
to an article of manufacture can be the subject of a design patent.
Ideas and abstract concepts cannot be patented. Only inventions
that can be completely described so that they can be reproduced
by a person of similar skill in the art of the invention as the
inventor can be patented.
In addition, mathematical algorithms, physical phenomena, the laws
of nature, perpetual motion machines, and inventions against public
policy, such as doomsday devices cannot be patented.
8. What are the requirements of novelty and non-obvious?
Regarding novelty (originality), an invention cannot be patented
if the invention was known or used by others in this country, or
patented or described in a printed publication in this or a foreign
country, before the invention by the applicant for a patent. Similarly,
if the invention was patented or described in a printed publication
in this or a foreign country or in public use or on sale in this
country more than one year prior to the application for patent in
the United States, it cannot be patented
Regarding non-obviousness, an invention is non-obvious
if the subject matter sought to be patented would not be obvious
to someone of similar skill in the art of the invention as the inventor.
9. What happens if an inventor publishes an invention prior to filing
an application?
Once an invention is published; sold, shown to the public, or described
in a printed publication, the inventor has one year from the first
date of publication to file a patent application for the invention.
If an invention has been published for more than one year, it is
in the public domain.
10. What are the Functions of the United States Patent
and Trademark Office?
The United States Patent and Trademark Office (USPTO, “PTO”
or Office) is an agency organized under the U.S. Department of Commerce.
The goals of the PTO are to:
• Grant patents to protect the rights of inventors
• Register trademarks to protect the identities of businesses
• Advise and assist other agencies of the government in matters
involving intellectual property
• Promote industrial and technological progress through the
preservation, classification, and dissemination of patent information
The main functions of the PTO regarding new inventions are to:
• Examine applications and grant patents
• Publish and disseminate patent information
• Record assignments of patents
• Maintain search files of U.S. and foreign patents
• Supply copies of patents and official records to the public
• Provide training to practitioners and applicants on patent
statutes and regulations
11. Why do I need a patent attorney?
Hiring a patent attorney is not a requirement of the PTO. Inventors
are free to draft and submit their own patent applications, and
respond to office actions to eventually obtain a patent. However,
preparing patent applications and conducting proceedings before
the PTO can be a complex undertaking. Inventors frequently hire
patent attorneys familiar with patent laws, rules, and Office practices
and procedures to prosecute applications. Patent attorneys are also
skilled in obtaining broader protection for an invention
12. How to choose a patent attorney?
Patent Attorneys are licensed attorneys who are also licensed to
practice before the USPTO. Along with an expertise in patent law,
a patent attorney should have at least some understanding of the
technology used in an invention. For more inventions of more technological
complexity, patent attorneys with particular expertise in the technology
area of the invention may be necessary. Persons who are not licensed
with the USPTO as patent agents or attorneys are not permitted to
represent inventors before the USPTO.
13. What is the Document Disclosure Program –
DDP?
A method of establishing evidence of the date an invention was conceived
and reduced to practice. Disclosure Documents are retained for two
years and destroyed, unless, they are referred to in a separate
letter, or in a related patent application filed within those two
years.
14. What are the necessary parts of a non-provisional
patent application?
In order to be complete, a non-provisional patent application must
include: A complete written description of the invention, the parts
that comprise it and it is used – called a “specification”
– and any drawings necessary to help explain the specification.
An oath or declaration signed by the inventor or inventors. At least
one claim; and the statutory filing fee
15. What is the proof of submission of a patent application?
Properly submitted patent applications are examined for completeness,
and receive an application number and filing date. A filing receipt
is issued by the Office –usually within one to three months
– confirming the application number and filing date.
16. How is the filing date of an application for patent determined?
The filing date of an application for patent is:
a) The date on which a specification (including at least one claim)
and any drawings necessary to understand the subject matter sought
to be patented are received by the USPTO; or
b) The date on which the last part completing the application is
received in the case of a previously incomplete or defective application.
17. What is a provisional application for a patent?
A provisional application permits an applicant to obtain a priority
filing date for an invention. A provisional application must contain
a detailed description of an invention, including any drawings –
which may be informal – necessary to understand an invention;
along with the proper filing forms and filing fee.
Provisional applications have a one year duration, at which time
they become abandoned. There are no extensions of time or renewals.
However, any (non-provisional) patent application filed while a
provisional application is pending, on the same subject matter,
and claiming the priority of the provisional application, will be
able to use the filing date of the provisional.
If a non-provisional patent application is filed more than one year
after the provisional application, the non-provisional cannot avail
itself of the provisional filing date.
A provisional application is therefore an inexpensive way to obtain
a filing date, and the legal right to the phrase “patent pending.”
However, there are drawbacks to filing a provisional patent application.
First, provisional applications are not examined, thereby lengthening
the amount of time an application will be before the Office. Furthermore,
since the term of a utility patent is 20 years from the filing date,
the time period between filing a provisional application and a subsequent
non-provisional application reduces the life of the patent. In addition,
the 18 month publication date runs from the priority filing date,
which would also be the filing date of the provisional application.
Finally, provisional applications cannot be used in conjunction
with design patent applications, and a provisional application,
in and of itself, will not result in an issued patent.
18. Are all patent applications made public?
No. By default, the Patent Office publishes all applications 18
months after the filing date. However, an inventor may make a non-publication
request when a design or utility patent is filed, and the patent
office will not publish the application.
A non-publication request may be filed with a design or utility
application. Since provisional applications expire after one year,
they are never published. All issued patents are published.
19. How to protect the inventor’s interest against
misuse of the invention prior to the grant of the patent?
The filing of a patent application obtains a filing date for an
applicant, and the legal right to use the phrase “patent pending”
in conjunction with an invention. By affixing the words “patent
pending” to an invention, the inventor provides notice that
a patent is pending on the invention – that rights in the
invention are being claimed.
However, an inventor does not obtain patent rights in an invention
until a patent for the invention has been issued. Therefore, while
a patent is pending on an invention, the inventor does not have
the legal right to prevent others from making, using or selling
the invention.
20. How does the USPTO conduct examination
of patent applications?
Once a complete utility or design application for patent has been
submitted to the Patent Office, it is assigned for examination to
one of several examining technology centers. The application is
then assigned to an individual examiner. The examiner analyzes the
application to make sure that it meets the statutory requirements
for a patent. The examiner will then either object to, or allow
the application.
Once a decision has been reached by an examiner, an applicant is
notified of the examiner’s decision.
21. What is an Office Action?
An office action is a written statement by an regarding
an application. An office action may be a notice of allowance, or
an objection to the application. In the case of an adverse office
action, the reasons for the examiner’s rejection or objection
will be stated, and an applicant is given a limited time to correct
the application according to the office action, or make arguments
regarding the office action.
22. Can the applicant request for reconsideration
of decision?
Yes. The request for reconsideration must be made
in writing and must distinctly and specifically point out the supposed
errors in the examiner’s Office Action and should also reply
to every ground of objection and rejection in the prior Office action.
23. Can the inventor file an amended application
upon rejection of the first application?
Yes. The applicant must clearly point out why he or
she thinks the amended claims are patentable in view of the objections
made by examiner in the Office Action. He or she must also show
how the claims as amended avoid such references or objections.
24. What is Final Rejection?
After the second or later consideration, the decision to reject
(or other action) the patent application is made final. The applicant’s
reply is then limited to an appeal in the case of rejection of any
claim and further amendment is restricted. Petition may be taken
to the Director in the case of objections or requirements not involved
in the rejection of any claim.
25. Can an application for amendment be
filed after the Final Rejection?
Yes. After final rejection or action, amendments may be made by
canceling claims or complying with any requirement of form which
has been made in an Office action. However, no amendment can be
made as a matter of right in appealed cases. After decision on appeal,
amendments can only be made as provided in the rules.
26. What is interference?
Interference is the process initiated by the USPTO in order to establish
the veracity of the different claims as well as determine the ‘first
inventor’, when two or more applications filed by different
inventors stake claim to the same invention.
Interference proceedings may also be instituted between an application
and a patent already issued, provided that the patent has not been
issued, nor the application been published, for more than one year
prior to the filing of the conflicting application, and provided
also that the conflicting application is not barred from being patentable
for some other reason.
27. What is “conception of the invention”
and “reduction to practice?
Conception of the invention refers to the completion of the devising
of the means for accomplishing the result. Reduction to practice
refers to the actual construction of the invention in physical form.
28. What is Notice of Allowance?
Notice of Allowance is the written confirmation from the USPTO that
the patent application is considered allowable. This can be made
either at the first stage of examination or during subsequent stages
of reconsideration.
The notice would also request the payment of the patent issue fee.
If the patent issue fee is not paid within three months from the
date of notice, the application will be regarded as abandoned.

29. Can patents be transferred or sold?
Yes. A patent is personal property and may be transferred, sold,
mortgaged, bequeathed by a will or passed to the heirs of a deceased
patentee. The patent law provides for the transfer or sale of a
patent, or of an application for patent, by an instrument in writing.
30. What is an assignment?
An assignment is a written instrument through which a patent can
be transferred, sold, mortgaged etc. as any other personal property.
The assignee, when the patent is assigned to him or her, becomes
the owner of the patent and has the same rights that the original
patentee had.
An assignment, grant, or conveyance of any patent or application
for patent should be acknowledged before a notary public or officer
authorized to administer oaths or perform notaries’ acts.
31. What are the common types of assignments?
The patent may be transferred in full or in part. There may also
be a grant that conveys the same character of interest as an assignment
but only for a particularly specified part of the United States.
A mortgage of patent property passes ownership thereof to the mortgagee
or lender until the mortgage has been satisfied and a retransfer
from the mortgagee back to the mortgagor, the borrower, is made.
A conditional assignment also passes ownership of the patent and
is regarded as absolute until canceled by the parties or by the
decree of a competent court.
32. When to notify the assignments with the USPTO?
An assignment, grant, or conveyance of any patent or application
for patent should be acknowledged before a notary public or officer
authorized to administer oaths or perform notaries’ acts.
The details of the assignment, grant, or conveyance of a patent
or an interest in a patent (or an application for patent) must be
notified to the USPTO within three months from its date.
33. Can there be joint ownerships of patents?
Yes. Patents may be owned jointly by two or more persons and joint
owner of a patent, no matter how small the part interest, may make,
use, offer for sale and sell and import the invention for his or
her own profit provided they do not infringe another’s patent
rights, without regard to the other owners, and may sell the interest
or any part of it, or grant licenses to others, without regard to
the other joint owner, unless the joint owners have made a contract
governing their relation to each other.
34. Can the patents be licensed?
Yes. The owner of a patent may grant licenses to others. A patent
license agreement is in essence nothing more than a promise by the
licensor not to sue the licensee. No particular form of license
is required; a license is a contract and may include whatever provisions
the parties agree upon, including the payment of royalties, etc.
35. What is infringement of patents?
Infringement of a patent is the unauthorized making, using, offering
for sale, or selling any patented invention within the United States
or U.S. Territories, or importing into the United States of any
patented invention during the term of the patent.
If a patent is infringed, the patentee may sue for relief in the
appropriate federal court and ask the court for an injunction to
prevent the continuation of the infringement and may also ask for
an award of damages.
36. What is Patent Marking?
Patent Marking is the marking of the word “Patent” along
with the number of the patent, done by a patent holder or his licensed/authorized
representative, who makes or sells patented articles. Failure to
do this would mean that the patentee may not recover damages from
an infringer, unless the infringer was duly notified of the infringement
and continued to infringe after the notice.
37. What are ‘Patent Pending’
and ‘Patent Applied For’?
“Patent Applied For” or “Patent Pending”
are phrases to give information that an application for patent has
been filed in the USPTO. However, these do not have any legal effect.
The protection afforded by a patent will start only upon the actual
grant of the patent.
38. What is the Paris Convention for the Protection
of Industrial Property?
It is an international treaty accepted by more than 140 countries,
including the United States. The basic tenets of the Paris Convention
for the Protection of Industrial Property are to:
• Provide the same rights in patent and trademark matters
that it gives to its own citizens to people from other countries
as well.
• Provide for the right of priority in the case of patents,
trademarks and industrial designs (design patents). This gives the
applicant the right to apply for protection in all the other member
countries, within a certain period of time, based on a regular first
application filed in one of the member countries. These later applications
will be regarded as if they had been filed on the same day as the
first application, provided the subsequent applications are filed
within 12 months in the case of first applications for patent and
six months in the case of industrial designs and trademarks.
39. What is Patent Cooperation Treaty?
The Patent Cooperation Treaty signed in Washington, D.C., in June
of 1970 and which came into force on January 24, 1978, has more
than 90 signatories now. The basic tenet of the Treaty is to facilitate
the filing of applications for patent on the same invention in member
countries through centralized filing procedures and a standardized
application format.
The timely filing of an international application affords applicants
an international filing date in each country which is designated
in the international application and provides (1) a search of the
invention and (2) a later time period within which the national
applications for patent must be filed.
40. Is the US patent valid in a foreign country?
The patents from USPTO are valid within the territory of the United
States and have no effect in a foreign country. An inventor who
wishes patent protection in other countries must apply for a patent
in each of the other countries or in regional patent offices.
41. Can an inventor in US file for a foreign patent before a
patent application is made for grant of the US patent?
Yes. But, the applicant will need a license from the Director of
the USPTO before applying for a patent in a foreign country. Such
a license is also required if the foreign application is to be filed
before the expiration of six months from the filing of an application
in the United States, unless a filing receipt with a license grant
is issued earlier.
A license is not required after six months of the U.S. filing unless
the invention has been ordered to be kept secret. In such a case,
the consent to the filing abroad must be obtained from the Director
of the USPTO during the period the order of secrecy is in effect.
42. Can foreign applicants apply for patents in US?
The patent laws of the United States make no discrimination with
respect to the citizenship of the inventor. Any inventor, regardless
of his or her citizenship, may apply for a patent on the same basis
as a U.S. citizen.
43. How can foreign applicants apply for the US Patent?
Foreign applicants can apply for US patents. The important facts
to be kept in mind are:
• If any application for patent has been filed in any foreign
prior to the application in the United States, the applicant should
provide copy of the foreign application certified by the patent
office of the country in which it was filed is to secure this right
of priority.
• If no claim for foreign priority is made, details of all
similar inventions filed more than a year before the filing in the
United States should be included in the oath or declaration.
• An applicant in a foreign country can make the oath or affirmation
before any diplomatic or consular officer of the United States,
or before any officer having an official seal and authorized to
administer oaths in the foreign country, whose authority shall be
proved by a certificate of a diplomatic or consular officer of the
United States.
• A foreign applicant can avail of the services of any patent
attorney or agent who is
44. Can a US patent attorney or agent represent a foreign
applicant?
Yes. Any patent attorney or agent, who is registered to practice
before the United States Patent and Trademark Office, can represent
foreign applicants.
45. Why are patents necessary?
Patents are important because it offers the following incentives
and benefits to the inventors:
• Recognition for their creativity
• Financial reward, if the invention is commercially viable
The patents encourage further and continuous innovations that help
to improve the quality of our lives.
46. What are the
rights of a patent owner?
The patent gives the holder, the right to decide as to who can use
the patented invention for the period in which the invention is
protected. The invention cannot be made, used, distributed or sold
without the authorization of the patent owner. The patent owner
is also conferred the right to transfer, sell, mortgage or license
the patent, just like any other personal property.
