Patent Preparation also knows as Patent Drafting is the first step in the process of obtaining a patent. Our team takes a comprehensive approach while drafting and preparing patent applications as it has the tendency to affect the short as well as long-term interests of the client.

Patent drafting contains various aspects such as the complete knowledge of the invention, technical subject matter, in-depth knowledge of various laws, a detailed description of the invention, and associates figures/drawings therefore it is a tough task.

A provisional specification and a complete specification are two different types of patent applications. The choice between these two types of patent applications depends on the level of research/idea conceptualization done by the inventor. If the inventor is having significant details related to his invention then a provisional specification is filed but it is subject to addition/modification in the future with further research. Filing a provisional application gives additional time to the investors to do research work and at the same time ensures protection to the invention of the inventor as the inventors are required to give full specifications along with claims within 12 months of the filing of an application.

In the case of the complete specification, the inventor can directly proceed with the filing after the research of invention is complete as it does not demand further research. .Drafting of a patent specification/application is a very vital and significant step in the process of patent application grants.

We at IP Legal Filings (IPLF) assure our clients of quality drafts every time as we have focused and experienced professionals having extensive techno-legal expertise in the drafting of patent applications in varied technology domains. IPLF has further configured a multi-level screening process in place that results in the patent specification of strong and enforceable quality.

What Is The Process?

1. Sign a non-disclosure agreement

The preliminary step in the drafting procedure is the signing of a Non-Disclosure Agreement with the Client, in order to offer an absolute declaration of confidentiality, and only then the project is started.

2. Invention disclosure form

After executing the Non-Disclosure Agreement (NDA) with the inventor, specialized(s) at IPLF obtain technical information/disclosure about the invention in an Invention Disclosure Form (IDF). The IDF has a set of questions regarding the invention that is required to be answered by the inventor(s).

3. Detailed discussion

After going through the IDF, a comprehensive discussion takes place between the patent professional and the inventor(s) to make sure that the professional has understood the invention in a similar sense as the inventor(s). Discussion between the inventor and patent professional can take place via face to face meetings, telephone conversations, or virtual meetings. This also helps in finalizing the drafting plan.

4. Drafting

Once our patent expert and the inventor are on the same page concerning the scope of the invention, the professional proceeds with the drafting of the specification with a suitable claim set, backed by a comprehensive technical description elaborating a variety of embodiments/examples of the invention. The purpose is to attain claims that are as broad as possible so as to reduce the risk of challenges that may be raised in respect of infringement based on prior arts.

Details Required

  • Applicant/Inventor Details
  • Power of Authority/Attorney
  • Invention Disclosure Form (IDF) of the invention
  • Detailed examples of invention

    Frequently Asked Questions

    1. What is the importance of Patent Drafting? Can an Inventor do the Drafting himself?

    Theoretically, the inventor can himself draft a patent application. But, as any good inventor who has, in turn, used a good patent drafting professional can vouch for, this is not the recommended course of action for any inventor serious about getting a patent. There is an appreciable difference between regular English writing/Technical writing and the language, form and expression of English involved in the Techno-Legal Disclosure of a patent. It can readily be appreciated that an inventor can describe his/her invention best. Whether that satisfies patentability requirements is a different matter altogether. Most inventors can describe usage of their inventions.


    A patent application has to describe in great detail how the invention is ‘enabled’, i.e., how can it be made and used so that a ‘POSITA’ – person ordinarily skilled in the art – can make and use the invention. Further, the invention has to be distinguished from the prior art in terms of structure rather than in terms of function. While writing the entire patent application is quite challenging, it is the claims that determine the scope of the patent. Writing broader claims than acceptable ones can invite objections based on close arts and writing narrower claims than needed shall prejudice the inventor’s interest if and when infringement occurs. As can be understood from above, it is extremely important to engage a patent professional for patent drafting owing to the stringent technical requirements and that of a fine balance of broad and narrow claims.

    2. What are the common mistakes done by Inventors in the process of Patent Drafting?

    Frequently, an inventor describes how useful his invention is without explaining clearly how it actually offers those advantages. For example, if an inventor invented a medicine composition which can cure a patient within 3-4 days of the dosage, rather than the average period of 15 days required by other similar medicines; writing only this would not help anyone in understanding the invention, or the inventor in getting proper protection.


    Mostly, inventors describe their invention only to the extent what they have actually done and, consequently, end up writing very ‘narrow’ claims. That is, such claims barely cover their invention, if at all, and can be easily ‘designed around’ by potential infringers. A skilled patent professional, however, can significantly widen the scope of the claims thereby granting much wider protection to the inventor. Another very common mistake committed by inventors is the usage of indefinite terms such as very long, very hot, etc. in claims. Such terms do not stand the test of indefiniteness and a patent claim that fails this test is deemed unpatentable, invalid, and unenforceable.


    Indeed a patent specification, and claims therein, is a document containing statements where even a comma put at the ‘wrong’ place can impact the situation dramatically when prosecution/ litigation happens, which is why it is always much better than a patent application be drafted by a patent professional with a good understanding of both the underlying technology and patentability requirements.

    3. What are the claims in a Patent Application?

    As has already been indicated, claims are the most important aspect of a patent application. While drafting a patent application, claims usually are on the last page. As said, the claims are the heart of a patent as they define the limits of exactly what the patent does, and does not, cover. The patent when granted gives the patentee the right to exclude others from making, using, or selling, only those things which are described by the claims (as finally granted).


    Writing claims is a fine balancing act. Broad claims have the lure of greater protection but, at the same time, the possibility of more challenges from existing prior arts. Narrower claims raise the fear of an invention easily being ‘designed around’ by others.


    A patent professional is well versed in treading this fine line and make the best efforts to get the invention to its maximum protection possible.

    4. Can the same claims be submitted in different countries where an invention is to be protected?

    The subject matter of the invention has a strong bearing upon this. For instance, while a method of treating human beings is not patentable in India, it is in the US. Again, while the method of treatment of humans is not patentable in India, the instrument used may be patentable. A patent professional is well-versed with such situations and can change application drafting and claiming strategies accordingly.

    5. Does the best method of performing the invention need to be disclosed in the Patent Specification?

    While the provisional specification has no such requirement, the complete specification has to Indeed it is in the interest of the inventor that the best method is described and appropriately claimed. Else others may just ‘design around’ the invention or the patent application (and the patent when granted) may be open to opposition or revocation.

    6. Can Traditional Knowledge be patented?

    Traditional knowledge is not patentable in India even though it may be patentable in other countries. Section 3 in India prohibits some inventions from being considered as inventions in India and traditional knowledge falls within that list under Section 3(p). You can refer to the IP India website for viewing this particular provision.

    7. What is First to File System?

    To fully understand this, this system needs to be compared with the first-to-invent system. In The first-to-invent system, whoever invents first gets the patent irrespective of who filed the patent application. In the first-to-file system, irrespective of who invented, whoever files the patent application first gets the patent. For instance, inventor A invents the machine but delays filing a patent application (that can even be a provisional application) for the same.


    Meanwhile, inventor B invents the same machine and files a patent application or the same. Thereafter, even if inventor A files a patent application, that filed by inventor B will act as prior art and so prevent inventor A from getting the patent.


    The first-to-file system is used in all countries including the United States, which switched to a first-inventor-to-file (FITF) system on March 16, 2013, after the enactment of America Invents Act. Prior to this, the US was following the first-to-invent system. The FITF system, in case of dispute, affords the first inventor a ‘grace period’ to file for his invention after public pre-filing disclosure. However, it is to be noted that such a ‘grace period’ is not granted in other jurisdictions that do not recognize such a period for disclosures made in advance of filing a patent application. In such a situation, an inventor’s public disclosure of his invention may stand as prior art against his own invention! To avoid such ambiguities, it is strongly recommended that an inventor file at least a provisional application as soon as he is ready with a sufficient description of at least the core idea that he wants to be protected.

    8. What happens if an Inventor admits something as already known?

    Any such admission, either during the drafting of a patent application or during the prosecution phase, qualifies as prior art. This again brings to the fore importance of good patent drafting, as well as appropriate drafting of various replies, etc. during the prosecution phase.

    9. Can drawings be submitted along with a patent application?

    Drawings may be submitted along with a patent application by the applicant himself (on his own cognizance) to further illustrate the invention, whereas drawings may also be needed if they are required to be submitted by the Patents Controller. Drawings can be submitted along with provisional or complete specification.

    10. How are patent rights enforced?

    Patent rights are usually enforced in a court on the initiative of the right owner. In most systems, a court of law has the authority to stop patent infringement. However, the main responsibility for monitoring, identifying, and taking action against infringers of a patent lies with the patent owner.

    11. What happens after filing a patent application?

    Once the patent application is filed, the following sequence of events happen:

    • The patent office reviews the application to determine if the application relates to national security or atomic energy. If it is so, secrecy directions are issued. Such directions are issued within 6 weeks of the filing.
    • The complete application is published after 18 months from the priority date.
    • The application is examined and an examination report is issued.
    • A response to examination has to be filed within 6 months from the date of issuance of the examination report.
    • In case the Controller/Examiner is not convinced by the reply, a hearing notice is issued by the Controller, which hearing needs to be attended and a reply to the hearing notice is to be filed within 15 days from the hearing date, based on which the final decision is taken by the Controller on the instant application.

    12. Are business methods patentable in India?

    In India, pure business methods are not patentable as set out under Section 3(k) of Indian Patent Act. They may be patentable under other jurisdictions. You can refer to the IP India website for viewing this particular provision.

    13. What is the difference between ‘Patented’ and ‘Patent Pending’?

    Patented or patent granted can be used only after a patent has been granted and not after only filing of application. However, after patent application filing, an inventor can use patent application pending, patent-pending and patent applied unless the patent application has been withdrawn/ refused/ abandoned.
