The dispute stems from a complaint (pdf) made by Canon in July accusing Avigilon of infringing US patent number 6,580,451, relating to image processing; 6,911,999, titled “Camera control system”; 7,321,453, called “Image input system”; and 9,191,630, named “Dynamic layouts”.
At the US District Court for the Eastern District of New York, Canon said the patents were infringed in several Avigilon security camera products.
However, on Thursday, October 5, Canon filed (pdf) a notice of voluntary dismissal, before re-filing a new complaint (pdf)at the US District Court for the Northern District of Texas, Dallas Division.
The new complaint accused Avigilon of infringing the same patents in the same products, but added US patent number 7,034,864, titled “Image display apparatus”, to the list of allegedly infringed inventions.
On the same day, Avigilon filed (pdf) a complaint for declaratory judgment at the US District Court for the District of Massachusetts.
Avigilon was seeking a ruling that it has not infringed the ‘451, ‘999, ‘864, ‘453 and ‘630 patents, and was also asking for a declaratory judgment of invalidity.
Avigilon stated that the patents should be deemed invalid and/or unenforceable “for failure to comply with one or more of the requirements of title 35 of the US Code, including without limitation, sections 101, 102, 103 and/or 112”.
