Some notable individuals from Pasadena include Dr. Meredith Groudine, who was born in New Jersey in 1929 and later studied at Cornell University. Later, he earned his Ph.D. in engineering science from the California Institute of Technology, where he worked on the development of a technology called electrogasdynamics. The technology, developed by Groudine, allows for the conversion of natural gas into electricity. It also has numerous applications in refrigeration and can reduce pollution from smoke. He holds more than 40 patents and is a member of the National Inventors Hall of Fame.

Inventors’ disclosures

Invention disclosures can help protect your intellectual property by letting potential licensees know about the existence of your invention before you file for a patent. In addition, disclosure can protect you against competing patent applications, particularly in the U.S., where the first-to-invent rule applies.

In addition, inventors who are working for a company are required to disclose their invention where their employer’s policies specify. In the past, inventors could also file for patent pending status by filing their invention disclosure with the USPTO. However, the USPTO decided this program was no longer necessary. Inventors used to file an invention disclosure because they thought it would provide them with the legal protection of patent pending status. Fortunately, there are other methods available for individual investors to gain patent pending status.

Inventors should consider their options before publicly disclosing their invention. Generally, an inventor has twelve months from the date of public disclosure to file a U.S. patent application. In other jurisdictions, disclosures are considered prior art, so it is better to file for patent protection as early as possible.
