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.

Non- Provisional Patent Drafting

A non-provisional patent draft is a techno-legal document describing the invention in-depth and discloses the best method of carrying out the invention. Thus, also known as a complete patent application.

It is directly filed before the patent office by either a patent agent or an inventor where the inventor wishes to protect the invention.

A Complete specification / non-provisional  specification can be filed with either of the following two options:

1. Direct filing – Complete specification is filed directly before the Indian Patent office without filing any corresponding provisional specification.

2. Subsequent filing-

  • The complete specification is filed subsequently after filing a corresponding provisional specification within 12 months of the provisional application.
  • Using the PCT route

Types Of Indian Patent Applications

An inventor can file the following types of Patent Applications before the Indian Patent Office:

1.Provisional Application
Provisional Application is a self-suggestive term i.e. temporary application filed with a Patent Office, to claim a “Priority Date” and when an invention is not complete in all aspects. It is less expensive to prepare and file and enables the inventor to study the feasibility of the invention in terms of potential markets, distributors, licensees. However the complete application needs to be filed within 12 months or else it will be treated as abandoned.

2.Complete Application
A patent application containing the complete specification and claims of the invention is called a complete application and this can be filed directly if the invention is complete in all aspects.

3.Convention Application
When an applicant files a patent application claiming a priority date based on the same or substantially similar application filed in one or more of the convention countries is known as a convention application.

An applicant should file the patent application in the Indian Patent Office within twelve months from the date of first filing of the similar application in the convention country to get “convention status” for the Indian Application.

4.Patent Cooperation Treaty (PCT) – International Application

An international application made in accordance with the Patent Cooperation Treaty (PCT) being the first application is called an international application, or PCT application.  An applicant needs to file just a single application with one receiving patent office in order to simultaneously seek a patent in multiple (up to 138 countries) across the globe.

The application is to be filed in English language within 12 months from the date of filing in India.

5.PCT-National Phase Application

An international application made in accordance with the Patent Cooperation Treaty (PCT) being the first application, can enter the national phase in India within 31 months from the international filing date or priority date (whichever is earlier). This application is filed before the Indian Patent Office claiming the priority and international filing date is called PCT National Phase application.

6. Divisional Application

When patent claims more than one invention, the applicant either voluntarily or in response to an objection based on lack of unity during the examination of the parent application at any time before the grant of the parent application can divide the parent application into two or more applications is known a Divisional Application.

The priority date for all the divisional applications is same as the Parent Application and it contains matter from a previously filed parent application.

7. Patent Of Addition

Any improvements or modifications in the patented invention as a natural process or as a result of feedback of the market or the industry then the original patented product or the process is protected by a “Patent of Addition” in India.

A patent of addition is only granted after the grant of the patent for the main inventions.

c
A provisional patent application is not examined, so its claims not get rejected in an office action. Depending on what was the problem that is being referred to as a rejection, a provisional application that fixes the problem might be subsequently filed with a later filing date

Provisional Patent Application

As per the patent law, a provisional application is a legal document filed in the Indian Patent Office or any other patent office to establish an early filing date and allows the inventor to file a patent application without a formal patent claim, oath or declaration, or any information disclosure (prior art) statement.

A provisional patent application buys you the time to file the complete patent application/ non- provisional patent application before the patent office within 12 months of filing while establishing the priority for the invention.

In simple words, a Provisional Application is a temporary, quick, inexpensive application filed before the Patent Office, to claim a “Priority Date” when an invention is not complete in all aspects and which can be claimed in a later-filed nonprovisional application.

Advantages of Provisional Patent Application:

  1. Easy preparation and filing
  2. Low Filing Cost,
  3. Protection of invention from getting copied
  4. Ability to use the term “patent pending”, which can only be legally used when a patent application has been filed
  5. Enabling the inventor to conduct a feasibility analysis of the invention in terms of potential markets, distributors, licensees.

A complete application/Non-provisional Application needs to be filed within 12 months or else the application will be treated as abandoned.

Freedom To Operate Search

Freedom to Operate Search, also known as Clearance Search or Right to use search is performed to check and identify whether any in-force patents or published patent applications with claims that cover the technology, process, or product the inventor is targeting.

Simply, it is used to ascertain the freedom to operate the invention in a particular jurisdiction from a legal point of view that the product or process utilized or carried out by the inventor is not infringing on any live patent’s claim.

If during the FTO search the invention to be operated is located on a live patent then the inventor may:

  • Not proceed with the invention
  • Invalidate the relevant patent
  • Apply for a license for the relevant patent
  • Buy the relevant patent technology

                                                                                                                 

Why conduct FTO Search?

  1. To identify potential patent barriers and uncover licensing needs in commercializing the products or/and technologies.
  2. To know countries where the patent can be applied.
  3. To map out the technical field of the products, technologies, or processes.
  4. To conduct patent infringement risk assessments, assess the competitors in the same field.
  5. To evaluate the potential for “new”

                                                                                                                   

Our Approach

Before the commercialization of any product/technology, it is essential to conduct a due diligence process to examine the claims of in-force patents as a means of assessing your risk of potential infringement. Thus, an FTO search/ Clearance Search is conducted to locate any granted and alive (in-force) patents or patent applications ensuring that the desired product can be pitched in a specific market (jurisdiction) without infringing or violating anyone’s intellectual property rights within that particular region/country.

Our focus:

  1. In-force patents
  2. Published pending patent applications
  3. An exhaustive search on patent databases based on
  4. Keywords based Searching,

Infringement Searches

A patent is said to be infringed when a product/process violates the rights granted to a patentee by unauthorized making, using, offering for sale or selling the patented invention.

Is my product/process infringing other patents?

To determine infringement of a patent either by a product or a process, we have to analyze the subject patent claims. In particular, the patent claims define the scope of protection granted to a patent.

An in-depth, detailed analysis has to be conducted to find out whether the product/process infringes upon the rights of a patentee.

The product/process is compared with the elements/process steps of the subject patent claim to determine whether the claimed elements/steps exist in the product/process, infringing the patent. A patent is said to be infringed if all the elements of the independent patent claim are located in the product or the product follows the same process as claimed in the invention.

Thus if all the elements in the patent claim map on to the features of the product, the product is infringing upon the patent rights of the patentee.

If the product does not have at least one feature of the patent claim then the product does not infringe upon the patent rights of the patentee. This analysis is referred as infringement analysis/ product mapping/ claim mapping.

Why conduct Infringement Analysis?

Infringement Studies are conducted to determine and measure the scope of infringement in terms of future litigations, earning royalty and/or licensing opportunities.

We at IPR studio, offer strategic solutions to identify technology standards and/or potential products infringing your patent. We mine technical literature to identify products, systems, or services using a similar invention as claimed in the subject patent. The comparison of the infringing product with the subject patent claim is provided as Evidence of Use chart, Claim Chart in textual and/or graphical formats.

Evidence of Use

Evidence of Use (EoU) helps patent owners identify all the potentially infringing products in the marketplace. Our EoU charts focus on manuals, designs, press releases, news, and reviews available publically.

Identifying parts of the alleged infringement that may need to be further tested or reverse engineered is another key part of a good EoU.

We map patent claim elements to specific features of identified products/processes by Collecting, documenting, and properly citing the evidence to demonstrate the indication of the strength of patent infringement assertion.

Claim Charts

A patent claim chart is a visualization of all information of the claim broken down by its specific elements and analyzed to determine and prove infringement has occurred. 

Our Approach

  • Analyzing Patent- Preparing claim charts with independent claim
  • Identifying products, systems, or services using a similar invention claimed in the patent.
  • Mapping Identified elements with product literature, product specifications, patents, figures, and photos to the claims of the subject patent.

Example:

A patent for a table claiming that the table top can be electronically height adjusted and can slide up and down.

The approach to check whether your invented table infringes the patent by checking whether all the elements of the patent claim appear in your product, i.e. whether your table-top can be electronically height adjusted, and can slide up and down.

If your product has all the features of the claimed invention along with new additional features, even then your product infringes upon the patent.

If your product does not have at least one feature mentioned in the elements of the subject patent claim, then your product does not infringe upon the patent.

Mosaicing Indian Patent Law

As per the Indian Patents Act 1970, an invention is patentable when it satisfies the following criteria:

  1. It is novel

  2. It has an inventive step or it must be non-obvious

  3. It has Industrial applicability

  4. It doesn’t fall under section 3 and 4 of the Patents Act 1970.

A person skilled in the art accesses methodologies for evaluating inventive step based patent laws.

Mosaicing provides the patent examiner to evaluate inventive step in light of two or more pieces of prior art information in combination, provided that a person skilled in the relevant art could reasonably have been expected to combine such information.

‘Prior Art’ is any “state of knowledge existing before the priority date of the claimed application.” Inventive step is always determined in relation to any matter published in any document anywhere in the world or any use before the priority date of the claim.

Mosaicing of prior art documents is permissible in the determination of the inventive step.

IPO guidelines for mosaicing:

  1. Mosaicing of prior art documents is not followed in the determination of novelty

  2. The cumulative effect of the disclosures cannot be taken into consideration nor can the lack of novelty be established by forming a mosaic of elements taken from several documents. This may be done only when arguing obviousness.

Case Law: In OA/8/2009/PT/CH [250/2012] IPAB held – “to defeat novelty, the appellant should show that an earlier document, disclosed all that the patentee is seeking to patent. And that each limitation of the claimed invention is found in a single prior art reference. The appellant has not done this. So the attack on novelty is rejected.”

A mosaic of extracts culled from several documents has not been accepted as constituting a relevant anticipation (Decision of the Controller (1942) Re. Patent Application No. 27709).

A ‘mosaic’ of separate steps, each known in manufacture, is not sufficient to constitute ‘anticipation’ as to warrant the refusal of grant of a patent, though they may have a bearing upon the question of quantum of ingenuity which arises when a court is called upon to consider whether there is ‘subject matter’ for a patent in the invention (Decision of the Deputy Controller (1946) Re. Patent Application No. 32384.)

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.
