A patent attorney can draft the letter to the point with the right technicalities and correct phrases while keeping it discreet and easy to understand.

This kind of a draft is acceptable with the legal bodies as they can get the entire description precisely and in a short amount of time.

Four Common Mistakes with Patent Drafting:

  1. Describing the Function of the Invention

It is ideal to describe the functionality and its working specifics of the invention rather explaining the output that it will deliver. The output delivered by the invention is of no use to the patent examiner rather than to know how the invention is made or how unique it is.

  1. It should not be vague or simple

The most prominent mistake that happens is that when inventors describe how easy it was to create the invention, the dispute lies as such, if the invention is that easy to explain then it can’t be deemed patentable as the invention will become obvious. Key objective is to describe a simple invention with utmost details, its uniqueness, and productivity as compared to the existing inventions.

  1. Too Specific

While describing the materials that are used in the process or invention you should not get all technical right from the start, first, start with general technicalities and then get to specifics. For example, if the invention requires a glass you could say only that. That is probably too vague. If you say it needs a metallic glass that is more accurate, which is appropriate. The main significance lies in how the glass is hardened, specifically? Other materials/process can be used to create a similar property such as strengthened molecular ion. A precise description is, “a hardened glass material made by diffusing with chemical/metal substances, such as but not limited to, palladium, ion diffusion, or annealing.”

  1. Word Placement

Poor choices in wording can lead to blunders. Grammatical errors can drastically change the understanding of the patent.  Patent proofreading services.

For example, using the wrong preposition proved very costly to a company Chef America, Inc., it owned a patent on a baking process to make dough based products i.e. verbatim, the process that was patented was: “to be heated to about 400° F to 850° F.” When a rival company Lamb-Weston developed a similar iteration of product and its patented process was: “the dough was to be baked “at” 400° F”. Chef America, Inc. sued for infringement. The case didn’t make it through as the patent claim literally required the dough to be heated up to 850 degrees Fahrenheit and not “at 400° F”.

  • Can an inventor draft his/her own patent?

An inventor can write his own patent. Given that inventor is well versed with the terminologies and the claim grammar that has to be used. If not, then it is not recommended as the application will be denied. Moreover, the cost of filing is quite high, and even if you are successful, the scope of the patent is likely to be inaccurate leaving the patent vulnerable to action. It is better to hire a patent attorney to improve the chances of success of getting a patent and to make it sustainable as well.

  • Is the usage of a patent drafting software a viable option?

The definite review cannot be made because no matter how advanced and innovative the software is it cannot perform as good as the council and collaboration of an experienced patent attorney. Hence, it is advised to read the instructions carefully prior to use for filing patent claims.

  • I have a provisional patent. Do I need to file for a non-provisional patent?

A provisional patent application doesn’t issue a patent. You will be granted a pending patent status, after which further procedures have to be done in order to move from a pending stage to a full issuance of the patent. The sole purpose of a provisional patent is to give a filing date to the applicant who can later use that to claim priority during the formal non-provisional application.

  • Is there a deadline for filing a non-provisional patent?

To claim the benefits of a provisional patent application, a non-provisional patent must be drafted with the USPTO within one year of the original provisional filing date, or the benefit is lost.
