U.S. Patent and Trademark Office sides with South-Tek Systems overturning U.S. Patent No. 9,186,533

WILMINGTON, NC – On January 11th, 2018, the U.S. Patent office sided with South-Tek Systems and invalidated all claims of the Engineered Corrosion Solutions (ECS) Patent Number 9,186,533 as being obvious to one of ordinary skill in the art of fire protection sprinkler systems. This means that prior art, such as publications and patents, demonstrated all of the elements that ECS claimed as an “invention”.

Prior to this decision, in July, 2016, South-Tek Systems filed a petition with the Patent Office to request an inter partes review (IPR) contending that the asserted ‘533 Patent is invalid. An IPR is a legal proceeding within the Patent Office to review the claims of an issued patent and determine whether the patent is valid. The Patent Office granted South-Tek’s petition and instituted an IPR for the ‘533 Patent. The Patent Office only grants a petition when there is a reasonable likelihood that one or more claims of the patent are invalid. In conclusion, the Patent office agreed with South-Tek Systems in that there was nothing inventive in the ‘533 Patent given what was already known in the industry.
