Kaspersky, which makes antivirus and Internet security software, has won its case against patent troll Lodsys.

Lodsys decided over the weekend to dismiss its case against Kaspersky with prejudice. “Instead of facing a jury, Lodsys will slink away instead” as “it was an unconditional surrender., reports “ArsTechnica” (http://tinyurl.com/morup5j).

In 2011 Lodsys sues some iOS developers for using in-app purchasing systems that it claims violates patents it owns. The patent holding firm targeted small iOS developers with notices of patent infringement for providing in-app purchase and/or Apple App Store purchase links within their apps. Apple came to the defense of the developers.

Also, Martha Stewart recently sued Lodsys after the patent troll demanded a $20,000 settlement for Stewart’s allegedly infringing iPad apps.
