strange-patents-fart-padThere are a lot of euphemisms out there for something that usually smells quite foul … but now, with the patented Flat-D flatulence deodorizing pad, your farts don’t have to stink!

Already, the Flat-D products have a strong customer base, with some very flatulent, very happy clients claiming it has changed their lives. No doubt.

Here are few question asked to me during interview in 2013

This year i appeared for patent agent examination. I would like to post some of question asked to me during interview.

hoping this might help future aspirants.

Interview panel -“Tell me about yourself.”

Me- “My name is chaitanya. I am electronics and telecommunication engineer with a certification in embedded system design. I am presently working with Ubitech systems in pune as an embedded design engineer.  ”

Interview panel-” Why do you want to be a patent agent?”

Me-“Someday i want to file a patent for my self .”

Interview panel-” For that you don’t have to be a patent agent you can file a patent for yourself even without being a patent agent.”

Me-” Yes sir there is a provision for this in patent act. I studied patent act thoroughly and i gave this exam just to check my knowledge of patent act.

Interview panel-” So tell me what are not patent-able according to Indian patent act ?”

Me- ” Section 3 and Section 4 gives us clear ideas as to what are not patent-able in India . To list a few i would say

traditional knowledge, soft wares as it is, IC topology ,invention relating to atomic energy are not patent-able”

Interview panel-” Why soft wares are not patent-able ?”

Me- ” As i think soft wares are written and anything written or drawn falls into artistic category and according to patent act any artistic forms are not patent-able. there can be another logic to this also. Soft wares are basically implementation of mathematical formulas which are previously known and any traditional knowledge are not patent-able.”

Interview panel-“If soft wares are not patent-able then how can you protect it ?”

Me-” I can protect it by implementing it on a hardware to form a system then that system along with software can be easily patented. Otherwise i can go for copyright.”

Interview panel-“why software is patent-able in USA?”

Me- ” i have not read US patent act so i am not in position to answer this ”

Interview panel- “Can you file a patent for RTOS kernel?”

Me- “no”

Interview panel-“Can you file patent for library function ?”

Me- “No”

Friends these were few questions (which i can still remember ) asked to me during my interview.

P.S. = I have posted the answers given by me and i can’t guarantee that all my answers are correct.

please comment if you feel my answers are wrong, with correct answers and justification.

happy to help

Patent Agent: A short note.

The controller general of patent maintains a register which contains the name address and other relevant information of all the registered patent agent in India. According to law of land here are eligibility criteria as to who can get their names registered as patent agent in india :

  • He/she must be citizen of India.
  • He/she must be above 21 years of age.
  • He/she must be a science/engineering/technology graduate from any recognized university.
  • He/she must pass the qualifying exam.

Point to note here is that any person who has worked as an examiner or controller of patent for not less than 10 years are also eligible to get their names registered as patent agent provided they don’t hold office at the time of application.

Rights of a patent agent

  • He/she can practice before controller of patent.
  • He/she can draft all the documents , make application and carry out other business as prescribed with any any proceedings before controller of patent.

It should be noted here that patent agent can act only if he has written consent from the person concerned (inventor or applicant ).

No person or company can disclose themselves as patent agent unless they are registered as patent agent in the register of controller of patent. Controller may remove or restore name of any patent agent in the register at any time. The controller may also refuse to deal with a patent agent on the grounds that he is either not a resident of India, convicted by law of land,  on removal of name from register or the person is acting as manager or director of a company making application for a patent.

Amenndment : short note

Amendments (in 1999, 2002, 2005, 2006) were necessitated by India’s obligations under TRIPS, allowing product patents in drugs and chemicals. Another important feature was the introduction of pre-grant representation (opposition) in addition to the existing post-grant opposition mechanism. The pre-grant representation has had success in a short span. One example is the abandonment of a patent application by Novartis on Glivec (Imatinib Mesylate), revoking the earlier granted EMR on the same drug used to treat Leukemia.
A controversial provision of this amendment was on software patent-ability, which was later withdrawn in another amendment (Patents Act, 1970, as amended by Patents (Amendment) Act, 2005). It is clear from the legislative history and interpretation of provisions in the Patent Act, 1970 (as amended in 2005) that the Patent office should not allow intrinsic patent-ability of computer programs. But there is evidence suggesting that the Patent office has acted otherwise. Patent Rules 2003 were amended in 2005 and again in 2006. Some of the important features of both the 2005 & 2006 Rules are the introduction of reduced time lines and a fee structure based on specification size and number of claims, in addition to a basic fee.
‘Though clause (k) of Section (3) of the Indian Patent Act holds computer programmes ‘per se’ or algorithms as non-patentable, technical ‘application of software’ or ‘software combined with hardware’ including embedded systems, may be granted patent’ .
