Seattle firm Implicit Networks is suing Adobe, IBM, Oracle and SAP for patent infringements.

Implicit Networks accuses the four of infringing two separate patents related to speeding up security processes on servers.

The company wants a royalty payment and is not seeking to stop sales of the products, which include IBM's WebSphere Application Server, Oracle's Application Server, SAP's NetWeaver and Adobe's JRun and ColdFusion software, according to Bloomberg.

Back in February Implicit filed against AMD, Intel, Nvidia, RealNetworks and Sun over a different alleged patent infringement. ®
