What is a patent?

A patent in an exclusive right granted by a country to the owner of an invention to make, use, manufacture and market the invention, provided the invention satisfies certain conditions stipulated in the law. Exclusivity of right implies that no one else can make, use, manufacture or market the invention without the consent of the patent holder. This right is available only for a limited period of time. However, the use or exploitation of a patent may be affected by other laws of the country which has awarded the patent.

These laws may relate to health, safety, food, security etc. Further, existing patents in similar area may also come in the way. A patent in the law is a property right and hence, can be gifted, inherited, assigned, sold or licensed. As the right is conferred by the State, it can be revoked by the State under very special circumstances even if the patent has been sold or licensed or manufactured or marketed in the meantime. The patent right is territorial in nature and inventors/their assignees will have to file separate patent applications in countries of their interest, along with necessary fees, for obtaining patents in those countries.

What is expected from patentee as an obligation to the state?

A patentee must disclose the invention in a patent document for anyone to practice it after the expiry of the patent or practice it with the consent of the patent holder during the life of the patent.

What are the conditions to be satisfied by an invention to be patentable?

An invention must satisfy the following three conditions of :

(i) Novelty (ii) Inventiveness (Non-obviousness) (iii) Usefulness

Novelty : An invention will be considered novel if it does not form a part of the global state of the art. Information appearing in magazines, technical journals, books, newspapers etc. constitute the state of the art. Oral description of the invention in a seminar/conference can also spoil novelty. Novelty is assessed in a global context. An invention will cease to be novel if it has been disclosed in the public through any type of publications anywhere in the world before filing a patent application in respect of the invention. Prior use of the invention in the country of interest before the filing date can also destroy the novelty. Novelty is determined through extensive literature and patent searches. It should be realized that patent search is essential and critical for ascertaining novelty as most of the information reported in patent documents does not get published any where else.

Inventiveness (Non-obviousness) : A patent application involves an inventive step if the proposed invention is not obvious to a person skilled in the art i.e., skilled in the subject matter of the patent application. The prior art should not point towards the invention implying that the practitioner of the subject matter could not have thought about the invention prior to filing of the patent application. Inventiveness cannot be decided on the material contained in unpublished patents. The complexity or the simplicity of an inventive step does not have any bearing on the grant of a patent. In other words a very simple invention can qualify for a patent. If there is an inventive step between the proposed patent and the prior art at that point of time, then an invention has taken place. A mere 'scintilla' of invention is sufficient to found a valid patent.

Usefulness: An invention must possess utility for the grant of patent No valid patent can be granted for an invention devoid of utility.

What are the types of inventions which are not patentable in India?

An invention may satisfy the condition of novelty, inventiveness and usefulness but it may not qualify for a patent under the following situations:

1. an invention which is frivolous or which claims anything obviously contrary to well established natural laws;
2. an invention the primary or intended use or commercial exploitation of which could be contrary to public order or morality or which causes serious prejudice to human , animal or plant life or health or to the environment;
3. the mere discovery of scientific principle or the formulation of an abstract theory or discovery of any living thing or non-living substance occurring in nature;
4. the mere discovery of any new property or new use for a known substance or of the mere use of a known process, machine or apparatus unless such known process results in a new product or employs at least one new reactant;
5. a substance obtained by mere admixture resulting only in the aggregation of the properties of the components thereof or a process for producing such substance;
6. the mere arrangement or re-arrangement or duplication of known devices each functioning independently of one another in a known way;
7. a method of agriculture or horticulture;
8. any process for medicinal, surgical, curative, prophylactic, diagnostic, therapeutic or other treatment of human beings or any process for a similar treatment of animals to render them free of disease or to increase their economic value or that of their products;
9. plants and animals in whole or any part thereof other than microorganisms but including seeds, varieties and species and essentially biological processes for production or propagation of plants and animals;
10. mathematical or business method or a computer program per se algorithms
11. a literary, dramatic, musical or artistic work or any other aesthetic creation whatsoever including cinematographic works and television productions;
12. a mere scheme or rule or method of performing mental act or method of playing game;
13. a presentation of information
14. topography of integrated circuits
15. an invention which, in effect, is traditional knowledge or which is an aggregation or duplication of known properties of traditionally known component or components
16. inventions relating to atomic energy

When should an application for a patent be filed?

Filing of an application for a patent should be completed at the earliest possible date and should not be delayed. An application filed with provisional specification, disclosing the essence of the nature of the invention helps to register the priority by the applicant. Delay in filing an application may entail some risks like (i) other inventors might forestall the first inventor by applying for a patent for the said invention (ii) there may be either an inadvertent publication of the invention by the inventor himself/herself or by others independently of him/her.

Can a published or disclosed invention be patented?

No, publication of an invention in any form by the inventor before filing of a patent application would disqualify the invention to be patentable. Hence, inventors should not disclose their inventions before filing the patent application. The invention should be considered for publication after a patent application has been filed. Thus, it can be seen that there is no contradiction between publishing an inventive work and filing of patent application in respect of the invention.

What is considered as the date of patent?

The date of patent is the date of filing the application for patent (whether provisional or complete). The term of the patent is counted from this date.

What is the term of a patent in the Indian system?

Term of the patent is 20 years from the date of filling for all types of inventions

How does one keep a patent in force for the full patent term?

A patent has to be maintained by paying the maintenance fees every year. If the maintenance fees is not paid, the patent will cease to remain in force and the invention becomes open to public. Anyone can then utilize the patent without the danger of infringing the patent.

What are the essential patent documents to be generated and submitted by a potential patentee?

There are two types of patent documents usually known as patent specification, namely

(i) Provisional Specification and (ii) Complete Specification

Provisional Specification

A provisional specification is usually filed to establish priority of the invention in case the disclosed invention is only at a conceptual stage and a delay is expected in submitting full and specific description of the invention. Although, a patent application accompanied with provisional specification does not confer any legal patent rights to the applicants, it is, however, a very important document to establish the earliest ownership of an invention. The provisional specification is a permanent and independent scientific cum legal document and no amendment is allowed in this. No patent is granted on the basis of a provisional specification. It has to be a followed by a complete specification for obtaining a patent for the said invention. Complete specification must be submitted within 12 months of filing the provisional specification. This period can be extended by 3 months. It is not necessary to file an application with provisional specification before the complete specification. An application with complete specification can be filed right at the first instance.

Complete Specification

Submission of complete specification is necessary to obtain a patent.

What are the criteria for naming inventors in an application for patent?

The naming of inventors is normally decided on the basis of the following criteria:

1. All persons who contribute towards development of patentable features of an invention should be named inventor(s).
2. 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).
3. A person who has not contributed intellectually in the development of an invention is not entitled to be included as an inventor.
4. A person who provides ideas needed to produce the ‘germs of the invention' need not himself / herself carry out the experiments, constructs the apparatus with his/her own hands or make the drawings himself/herself. The person may take the help or others. Such person who have helped in conducting the experiments, constructing apparatus or making the drawings or models without providing any intellectual inputs are not entitled to be named inventors.
   
   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 recorded of daily work done by them in the form of diary. The pages in the diary should be consecutively numbered and the entries made be signed both by the scientists and the concerned leader.

What is the nature of information needed while consulting a patent attorney?

As an inventor one should share the complete invention with a patent attorney in the same manner as a patient confides in a doctor. A s a doctor may not be able to write a correct prescription without knowing the details of the disease/problem, a patent attorney may not be able to draft a good specification in the absence of details about the invention. Following points should be kept in mind while discussing with the attorney:

1. Provide complete details of the invention including failures, if any, on the way to the invention.
   
   Do not feel bad if attorney asks you questions like where did you get the idea from or did you copy the idea from somewhere or are you keeping other inventors working with you on the inventorship or have you published the invention or disclosed it in a seminar/conference or have you displayed the invention in an exhibition? A patent document is a techno-legal document, hence all precautions are to be taken right from the first step. Provides right answers and you may even show your laboratory note book/log book to the attorney. This will help the attorney / agent to explain the inventive step in a precise manner and draft a good specification and associated claims.
   
2. Explain the central theme of the invention and novelty, inventiveness and utility of the invention.
   
3. Share all the prior art documents in your possession with the attorney.
   
4. If you have developed an improved version of your competitor's product/process, admit it and be totally honest. This would help the attorney in drafting precise claims and avoid excessive claims, which might be struck down immediately or at a later date.
5. A detailed description of the best way of putting the invention into practical use, results of your tests and trials, etc., including all failures and defects should be given to the attorney.
6. Alternative ways of using the invention, and the substitutes or parts of it i.e., will one chemical compound do as well as any other in the process?
   
7. It may be worth drafting the patent widely enough to cover less satisfactory alternatives as well so as to prevent rivals from marketing a less satisfactory competing product which because of its defects might bring the whole genre of product into disrepute or which may be cheap.
   
8. Both after an initial search and during the course of the filing and grant of a patent application, it is important to respond quickly and accurately to queries which the patent attorney may have. Thus the client should keep the patent attorney informed of any new developments in the field of invention carried by the patentee or some one else.

What is opposition under the Indian Patents Act 1970?

After the Patent Office has examined an application and found it in order forgrant of a patent, it publishes the title pf the invention, name of the inventor(s) and the applicant(s), abstract of the invention, drawings and claims in the Gazette of India, Part III Section 2, for interested parties to oppose the grant of the patent. An application for opposition may be filed at the concerned Patent Office branch within four months of the date of the issue of the concerned gazette. An extension of one month is possible; a request for extension has to be made within the first four months. Typed or photocopies of the specification together with photocopies of the drawings, if any, can be obtained from the Patent Office, Calcutta or the concerned branch office on payment of the prescribed fees. One would like to oppose if the idea of the accepted application infringes upon one's invention/existing patent, if the coverage of the proposed patent is very wide which may be detrimental to one's research or if the idea is not novel and so on.

Is a patent granted in one country enforceable in other countries?

No. There is nothing like a global patent or a world patent. Patent rights are essentially territorial in nature and are protected only in a country (or countries) which,has (have) granted these rights. In other words,-for obtaining patent rights in different countries one has to submit patent applications in all the countries of interest for grant of patents. This would entail payment of official fees and associated expenses, like the attorney fees, essential for obtaining patent rights in each country. However, there are some regional systems where by filing one application one could simultaneously obtain patents in the member countries of a regional system; European Patent Office is an example of a similar system.

Does grant of a patent in one country affect its grant or refusal in another country?

Each country is free to grant or refuse a patent on the bases of scrutiny by its patent office. This means that granting a patent in one country of the Union does not force other countries to grant the patent for the same invention. Also, the refusal of the patent in one country does not mean that it will be terminated in all the countries.

What is industrial property?

Industrial property includes:

(a) Patents (b) Utility models (c) Industrial designs (d) Trademarks, service marks and trade names (e) Indication of source or appellations of origin (this is same as the geographical indications adopted in TRIPS);

What do you understand by the right of priority and what is its significance?

The date from which patent right is deemed to start is usually the date of filing of complete specification. To obtain rights in other member countries, the application must be filed on the same day in other member countries if it is desired to have the rights started from the same day. However, there are practical difficulties in synchronizing the activities. For facilitating simultaneous protection in member countries, the Convention provides that within 12 months of national filing, if patent applications are filed in those member countries, the patents, if granted in member countries, will be effective from the date of national filing. This right is known as the right of priority. In other words you maintain the priority or the same date of filing in all the member countries and no one else in those countries can obtain the patent rights on a similar/identical invention from the same or a later date.

In case the applicant after a second look at the patent application finds that the patent contains more than one invention or on his own accord wishes to divide the application, he can claim the initial date of priority for subsequent patent applications. The applicant may also, on his own initiative, divide a patent application and preserve as the date of each divisional application the date of the initial application and the benefit of the right of priority, if any. Each country of the Union shall have the right to determine the conditions under which such division shall be authorized.

Priority may not be refused on the ground that certain elements of the invention for which priority is claimed do not appear among the claims formulated in the application in the country of origin, provided that the application documents as a whole specifically disclose such elements.

Are there any differences in the filing of patent applications in respect of microbiological inventions and other inventions?

An inventor is required to deposit the strain of a microorganism in a recognized depository which assigns a registration number to the deposited microorganism. This number needs to be quoted in the patent application. Obviously a strain of microorganism is required to be deposited before filing a patent application. It may be observed that this mechanism obviates the need of describing a microorganism in the patent application. Further, samples of strains can be obtained from the depository for further working on the patent. There are many international depositories in many countries, which are recognized under the Budapest Treaty.

What is the system for protecting microbiological inventions and microorganisms?

The Indian Patent Act has no specific provision for patenting of microorganisms and microbiological processes. However, as a matter of practice microorganisms per se are not patentable in India. (However, a recent decision of the Kolkata High Court has held that microbiological processes are patentable in India). In order to meet the obligation under TRIPS. India is required to introduce a patenting of microorganisms. Draft laws in this regards have been formulated. It may, however, be noted that many countries allow both process and product patents in regard to microbiological inventions and microorganism per se. all such countries allow patenting of genetically modified microorganisms but a few also allow patenting of naturally occurring microorganisms if isolated from nature for the first time and if other conditions of patentability are satisfied.

What is patent cooperation treaty (PCT)?

The patent cooperation treaty (PCT) is a multilateral treaty entered into force in 1978. Through PCT, an inventor of a member country (Contracting state of PCT can simultaneously obtain priority for his/her Invention in all/ any of the member countries, without having to file a separate application in the countries of interest , by designating them in the PCT application .India joined the PCT on December 7, 1998.

Who coordinates the activities of PCT ?

All activities related to PCT are coordinated by the World Intellectual Property Organization (WIPO) situated in Geneva.

What is the need for PCT ?

In order to protect your invention in other countries, you are required to file an independent patent application in each country of interest; in some cases , within a stipulated time to obtain priority in these countries .This would entail a large investment, within a short time, to meet costs towards filing fees, translation, attorney charges etc. In addition you are making an assumption which, due to the short time available for making the decision on whether to file a patent application in a country or not , may not be well founded .

Inventors of Contracting States of PCT on the other hand can simultaneously obtain priority for their inventions without having to file separate application in the countries of interest ; thus saving the initial investments towards filing fees, translation etc. In addition the system provides much longer time for filing patent application in member countries . The time available under Paris Convention for securing priority in other countries is 12 months from the date of initial filing. Under the PCT, the time available could be as much as minimum 20 and maximum 31 months. Further, an inventor is also benefited by the search report prepared under the PCT system to be sure that the claimed invention is novel. The inventor could also opt for preliminary examination before filing in other countries to be doubly sure about the patentability of the invention .

How are patent applications under PCT handled?

The patent office or nay other office designated by each contracting state becomes a receiving office for receiving patent applications These applications are referred to International Searching Authorities (ISA) which usually the patent offices, appointed to carry out the patent search on a global basis. In case the receiving office is also an ISA, a separate referral is not required . There is also a provision to get a patent application examined by international preliminary Examining Authorities which, in most cases are ISA.

Will an international application designating India be treated as an application for grant of patent under the 1970 Act?

Yes, an international application designating India shall be treated as an application for patent under the Act.
