Caltech is filing a lawsuit to Apple for its alleged infringement on the Wi-Fi chips from its four university patents. Last Thursday, Caltech argued that Apple knowingly used and advertised gains from patented technology in almost all of its major products from the iPhone 5 forward. In the hopes of blocking the sales of the products and to recover damages from the infringement, Caltech files the charges. However, Apple was unable to give any immediate comments.

The technology in question are the patents integral to the 802.11n and 802.11ac Wi-Fi which are two of latest standards. In layman’s term, these patents are supposed to “allow for faster data transmissions”. These patent which were granted between 2006 and 2012 also simplifies the hardware to achieve such data transfer speed.

The lawsuit also targets Broadcom as the manufacturer of the Wi-Fi chips used in the latest Apple devices. Apple is also in a sticky situation since they’re Broadcom’s biggest customers – representing about 14% of the company’s revenue.

Apple had the same situation with the University of Wisconsin-Madison last year. Paying damages worth $234 million for infringing a patent for processor performance. Universities are not in the habit for filing lawsuits to gain money from older patents, so this case may be well founded.
