Level 3 Communications has filed a patent infringement suit against Limelight Networks, alleging that Limelight's content delivery network infringes four Level 3 patents.
The filing cits patents 6,185,598; 6,473,405; 6,654,807 and 7,054,935, according to Dan Rayburn, streamingmedia.com EVP. Level 3 says it notified Limelight of the potential violations in February 2007, but that Limelight did not redesign its network to avoid infringing.
Given the notification by Level 3 and lack of response by Limelight, one has to assume Limelight thinks it is not infringing.
These days, it does not seem to be enough to have the right assets, people, channels, partners and technology. One often has to own intellectual property as well, if only to use as bargaining chips for cross licensing.
Hardware and software suppliers have known this for years. What is new is that service providers have to do the same.
