The Indian law of patents is enshrined in the Patents Act, 1970. The Act seeks to provide for legal protection for inventions. The rights granted under the Act, are operative in the whole of India.


The object of the patent law is to provides a statutory right to owner of the patent for a certain period of time and disclose invention to use it and practice that invention and make it work thus encourage scientific research and new technology, stimulate new inventions of commercial utility and pass invention into public domain after the expiry of the fixed period of the monopoly.


India is one of the countries party to the Paris Convention so the right of priority are applicable. The applicant may within the six months apply for protection.


A Patent is an exclusive monopoly patent lawyer cost granted to an inventor over his invention for a limited period of time. It provides an enforceable legal right to prevent others from exploiting an invention.


Patent represents one of the powerful intellectual property rights. The registration of a patent confers on the patentee the exclusive right to use, manufacture or sell his invention for the term of the patent. It means that the invention cannot be commercially made, used, distributed or sold without the patentee's consent. The patent rights can usually be enforced in a court of law.


Any person claming to be the true and first inventor of the invention;

Any person being the assignee of the person claming to be the true and first inventor in respect of the right to make such an application;

Any legal representative of any deceased person who immediately before his death was entitled to make such application Patent Search;

It is prudent to conduct searches as early as possible to avoid spending time and money re-inventing a known matter. A patent is not granted to an invention if it is already available with the public either in the form of published literature or common knowledge.


To be patentable, an invention must, in general, satisfy certain criteria. The invention must be of industrial applicability, must be new and must show an inventive step which could not be deduced by a person reasonably skilled in the field. Above all, its subject matter must be accepted as "patentable" under law. As for example, Inventions which are frivolous or claim anything contrary to well established natural laws are not patentable. There are also other specific categories of inventions which are declared as non-patentable.


The process of patenting typically involves conducting prior art searches to distinguish the invention and develop a description that illustrates the best method of working the invention. The description of the invention is called specification. Depending upon the sufficiency of the description a specification may be either provisional or complete Specification.


A provisional specification is often the first application filed in respect of an invention, and usually contains only a brief description of the invention. It need not contain claims. Compared with the provisional, the complete specification contains the full description of the invention, and the best method of making the invention work. The complete specification comprises a title, field of invention, the background of the invention, the description of the related art, drawbacks of the prior art, the summary of the invention, the brief description of the figures, the detailed description of the preferred embodiments, claims and abstract. Complete specification must be filed within 12 months from the date of filing of the provisional specification.

Claims are the most important component in the patent specification as it is the legal operative part which define and determine the legal protection sought for. The extent of patent protection for an invention shall be determined by the terms of the claims. The description and the appended drawings may be used to interpret the claims.


The procedure for the grant of a patent starts with filing of the patent application along with the prescribed fees at the patent office followed by filing of request for examination in the prescribed format, after the publication of the application. The applications are examined substantively and a first examination report stating the objections is communicated to the applicant. Application may be amended in order to meet the objections. If the applicant does not comply with the objection, the application will be abandoned. After complying off the requirements the application is published in the Official Journal. At that time, opposition can be filed on limited grounds, but hearing is not mandatory. Patent will be granted if the application is found to be in order. Then, the application and other related documents will be open for public inspection. Thereafter, at any time after the grant but before the expiry of a period of one year from the date of publication opposition on substantive grounds is available. The whole process typically takes at least two years.


The tenure for patents is 20 years from the date of filing of the application for the patent before the patent office. It is the responsibility of the patentee to maintain an issued patent by paying the annuities until the patent expires. After 20 years term the invention claimed in the patent falls into the public domain.


Restoration of a patent that lapses due to non-payment of renewal fees can be made within one year of lapse. However, certain limitations will be imposed on the rights of the patentee when the patent is restored.
