As Zynga (ZNGA +4.8%) preps its international gambling launch, the company is quietly building an arsenal of gambling-related patents. Research firm Envision IP notes Zynga recently obtained 38 patents from R&D lab/patent troll Walker Digital, and that 33 of them are gambling-related. Altogether, Zynga is now believed to have 89 U.S. patents and 36 applications. Does the company plan to use this IP to simply differentiate its offerings, or to stamp out would-be rivals?
