Patent of the Month

Limb Prosthesis

United States Patent 8778031

Disclosed are limb prostheses for use when normal use of the lower leg is temporarily or permanently lost due to lower leg injury or disease, including below-knee amputation. Disclosed prostheses provide full body weight support and allow a wearer to maintain the use of the hands and arms during ambulation. In addition, a wearer can maintain use of their own knee to flex and extend during ambulation, thereby better controlling the prosthesis during motion and providing a more normal gait as compared to previously known devices. In the event of permanent loss of the lower leg due to below-knee amputation, the disclosed prosthesis provides an alternative to socket-type prosthetic devices.

What is a Patent

A patent is an intellectual property right granted by the Government of the United States of America to an inventor “to exclude others from making, using, offering for sale, or selling the invention throughout the United States or importing the invention into the United States” for a limited time in exchange for public disclosure of the invention when the patent is granted.

The United States Patent and Trademark Office (USPTO) is the Federal Agency charged with granting U.S. Patents and registering Federal Trademarks.

 

Types of Patents

Utility patents may be granted to anyone who invents or discovers any new and useful process, machine, article of manufacture, or compositions of matters, or any new useful improvement thereof.  In general, the term of the patent is 20 years from the filing date.

Design patents may be granted to anyone who invents a new, original, and ornamental design for an article of manufacture.  Design patents remain in force for 14 years from the filing date.

Plant patents may be granted to anyone who invents or discovers and asexually reproduces any distinct and new variety of plants.  Term of the patent is 20 years from the filing date.

 

Types of Applications

Patent Application - Because there is not a simple form to complete to file a patent, each application is unique, and comprises a number of required forms

Provisional Application - provides simplified filing with a lower initial cost and one full year to prepare to file a "regular" (non-provisional) patent application.  Successful filing establishes an official United States patent application filing date for the invention, permitting the inventor to use the term "patent pending" for one year.  There is no such thing as a provisional patent - only a provisional patent application.
