Patent Prosecution

Patent prosecution is the patent process required to obtain a patent which involves interaction between the Assignee/Inventor or his legal representative and Patent Office with respect to his patent application. During the patent prosecution process, a patent application has to go through the following steps-

  • Filing of the Patent Application- An inventor can file patent application either online or offline at the patent office in any of the respective jurisdictions: Kolkata, Delhi, Mumbai, and Chennai.
  • Publication of the Application- After filing the patent application is published within18 months from the earliest priority date/ filing date of the application. Prior, to the publication the patent application is confidential to the patent office.
  • Request for Examination- A request for examination has to be filed within 48 months from the date of filing of the application or the date of priority whichever is earlier. Request for examination can be pertained either by normal examination route or by Expedited examination route.
  • First Examination Report- After the examination of the patent application by the patent controller/patent examiner a First Examination Report (FER) is issued to the applicant or authorized agent. The FER cites the deficiencies in the patent application in compliance with the Patents Act, 1970 along with the objections in terms of novelty/ inventive step/ industrial aplicability. 
  • Examination Response- The applicant or his legal representative has to draft a reply to FER within 6 months from the date of issuance of FER overcoming the objections cited by the patent examiner.
  • Hearing- Hearing is conducted between controller and patent applicant is to ensure that all objections raised in the patent application are resolved easing the grant procedure.
  • Grant of the Patent Application- When the patent controller/patent examiner is satisfied that the patent application meets all patentability requirements. The granted patent is notified in the patent journal which is published from time to time.
  • Renewal of the Patent Application- In order to keep the patent in force, a renewal fee shall be payable to patent office at the expiration of the second year from the date of the patent or of any succeeding year.
  • Opposition of Patent application- A patent application can be opposed by anyone after the publication of the patent application. There are two types of oppositions-
    • Pre Grant Opposition- Opposition made after publication until grant of patent application.
    • Post Grant Opposition- Opposition made within 12 months after grant of the patent application.

Invalidation Searches

Patent invalidity/validity search is basically the analysis to understand the strength of patent claims. A patent invalidity (or patent validity) search can be used to validate the claims made by a patent or to invalidate one or more claims of a competitor’s patent when facing a patent infringement suit. Moreover, these searches also check the strength of a granted patent while exploring licensing options.

The validity search is performed by after the grant of a patent to ensure validity and enforceability of the granted patent. On the other hand, invalidity search is conducted to invalidates the patent that has been or may be asserted.

The key objective of the validity and invalidity search is to point out prior arts which were likely to be overlooked by the patent examiner during the prosecution stage and questions novelty or non-obviousness of the patented invention.

It involves exhaustive and in-depth searching of the patent and non-patent literature search to identify prior arts predating the earliest filing of the patent.

Why conduct Invalidity Searches ?

  1. To determine novelty and inventive step of your patent over other patents.
  2. To invalidate patents when threatened with infringement.
  3. To prepare for licensing and enforcement of patents.
  4. To accurately understand the technology of patent and claims coverage.
  5. Upon receiving a notice from a patent owner for infringement.

OUR APPROACH-

We perform exhaustive searching across various databases and provide references that are relevant to the patent that has to be invalidated. Our comprehensive search strategy includes

Boolean Search

Boolean search is a type of patent searching that enables the users to find relevant results by combining keywords with Boolean operators. Boolean operators are used in all types of patent searching including the patentability search, validity/ invalidity search, prior art searching/ novelty search and the like.

What are boolean operators?

Boolean Operators are simple words used as conjunctions to combine or exclude keywords in a patent search.

General boolean operators are:

1.AND,

2.OR,

3.NOT

The above mention boolean operators are either used alone or in combination to produce focused and productive results by eliminating inappropriate hits.

LET US UNDERSTAND THE BOOLEAN OPERATORS

From the above, we can see if we use OR we have broader results while using AND the results are narrowed down. NOT excludes the results having that specified keyword.

Let us understand more with examples:

The pictorial snapshot illustrates applications containing tennis and applications containing a ball.

The pictorial snapshot illustrates applications containing both tennis and ball.

The pictorial snapshot illustrates results of applications containing either tennis or ball.

The pictorial snapshot illustrates applications containing ball but not the word tennis and applications containing the word tennis but not ball.

From the above examples, boolean searching can easily be understood.

Types of Patent Search Strategies

Different Approaches for Patent Searches

Different approaches for searching patent can be categorized under the following heads:

  • Keyword searches,
  • Classification searches,
  • Boolean Searches,
  • Structure searches,
  • Sequence searches, and
  • Image searches

Keyword Searches

The most widely used and basic search category for patent searching involves the use of concepts and terms related to the invention by inserting text characters as search terms. Search term includes alternative terms, synonyms, spelling variations, acronyms. It also helps in finding records related to similar technology area.

Classification Searches

Classification searches are performed used to categorize patents based on a specific code that groups inventions according to the technical area. It is an easy, comprehensive, faster and quicker way of classifying patents as per the subject matter.

Classification systems:

  • International Patent Classification (IPC),
  • United States Patent Classification (USPC),
  • Cooperative Patent Classification (CPC),
  • Japanese FI and F term classification, F stands for “feature”.

Earlier European Patent Classification (ELICA) was also used but to make the classification easier Cooperative Patent Classification (CPC) was introduced. CPC is an extension of the IPC and is jointly managed by the EPO and the US Patent and Trademark Office. 

The classification search is used in combination with other search strategies to yield the best search results to the searcher conducting a search in a particular technical area.

Boolean Searches

Boolean Search is a type of search allowing searches to combine keywords with operators such as AND, NOT and OR to produce more relevant results.

Structure Searches

Structure searches involve searching chemical structures on certain databases based on atom to atom and fragment to fragment indexing of chemical structures. 

Sequence Searches

Sequence searches are used for searching chemical structures on certain database based on nucleotide and protein sequences.

Image Searches

Image searches are conducted on Google platform which allows image to image mapping based on a search algorithm helpful in identifying similar images.

Why perform Patent searching?

Patent Searching is performed:

  • To determine the novelty of the invention and idea by finding similar patents and prior arts.
  • To discover owners of a particular patent or patents in a field of interest.
  • To validate and invalidate the particular patent searching.
