Utility Patent Application

A patent is a right granted by a government to an inventor to exclude others from making, using, offering for sale or selling the invention in that country (e.g., Canada, United States)  or importing the invention into that country for a limited period of time.

Utility Patents cover inventions that have a unique way of functioning and provide a useful result. These can be mechanical gadgets, manufacturing processes, microprocessors, software and any other device that are man-made.


A utility patent application consists of a detailed description of the invention and how it is made and works, along with claims and drawings. A utility patent prevents others from selling, using, and manufacturing the invention for a period of 20 years.

We provide:


  • A free and confidential initial consultation.


  • Patent Search and Patentability Opinion based on a prior art search using several databases (USPTP, CIPO, WIPO, IEEE, PubMed & etc.).  Our reports provide prior patents or other forms of literature that are similar to the inventor’s invention. We will also provide our opinion on whether the patent application may be accepted by the patent office or not.


  • Preparation of Patent Specifications and Claims: We also create a detailed description of the invention and prepare any needed drawings. The most important part of a patent application, are its claims. Proper claim drafting requires know-how and expertise. Our team of experts work in close interaction with the inventor to prepare strong and broad claims.


  • Filing and Communication with the Patent Office: A completed patent application will be filed with a patent office (US or Canadian Patent Offices, and patent offices in other countries through our collaborating law firms).  We also communicate with the patent office through the whole prosecution process, preparing amendments, and responding to any required changes by the patent office.

  • What is the difference between a design patent and a utility patent?


A utility patent is broader and includes how a product works as well as how it looks. It applies to just about any item, including chemical compounds, furniture, electronics, and many other products. A design patent only protects how the item looks. It's usually granted on items, such as furniture pieces or electronic devices, that are patented or have expired patents.
