Patent of the Month
Non-linear Electrical Actuation and Detection
A method and system is disclosed to detect and analyze an electric signal based on movement between an element and a counter electrode influenced by a nonlinear electric field produced by an electrical signal impressed between the element and counter electrode. The disclosed devices and methods may be employed to detect, for instance, presence of chemical/biological species in a sample or measure physical parameters of a sample such as pressure/acceleration, density, viscosity, magnetic force, temperature, and/or extremely small masses.
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 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.
To be eligible for a patent, an invention must be:
NEW - not known or used by others in this country or patented or described in a printd publication in this or a foreign country
USEFUL - must have a purpose, and it must operate to perform the intended purpose
UNOBVIOUS - must be sufficiently different from what has been used or described before and not obvious to someone skilled in the art of the technology related to the invention
