What Is the Patent Trial and Appeal Board?
The Patent Trial and Appeal Board (PTAB) is a tribunal within U.S. Patent and Trademark Office. The PTAB oversees trial proceedings, namely: inter partes review (IPR), post-grant review (PGR), covered business method (CBM) review, and derivation proceedings. The Board also hears appeals from adverse patentability decisions by patent examiners in original applications, reissues, and reexaminations. And, while phasing out since the passage of the America Invents Act (AIA) in 2011, the PTAB is also responsible for deciding interferences. The PTAB was previously referred to as the Board of Patent Appeals and Interferences and was renamed by the AIA.

What Is Trademark Infringement?
Trademark infringement is defined as the unauthorized use of a trademark or service mark. This use can be in connection with goods or services and may lead to confusion, deception, or a misunderstanding about the actual company a product or service came from. Trademark owners can take legal action if they believe their marks are being infringed. If infringement of a trademark is proven, a court order can prevent a defendant from using the mark, and the owner may be awarded monetary relief.

The United States Patent and Trademark Office refers to a trade secret as a type of intellectual property. This definition of trade secret is in reference to the business ownership of a formula, pattern, compilation, program, device, method, technique, or process that provides a competitive edge. As a member of the World Trade Organization, the U.S. government has a responsibility to protect trade secrets. The passage of the Defend Trade Secrets Act of 2016 (DTSA) also increased trade secret protection. Under the DTSA, an individual or organization may be found liable in a civil case for the misappropriation of trade secrets.
