Following recent suits against AOL and LinkedIn, Priceplay.com has sued Google for alleged infringement of two patents related to Internet-based transactions (8,050,982, 8,494,917). On the basis of assignment records, Priceplay appears to be controlled by inventor Wayne Lin. The two patents-in-suit are continuations of Lin’s earlier 6,978,253 patent and are the same patents that were asserted against AOL and LinkedIn. Priceplay contends that Google infringes the ‘982 and ‘917 patents by selling ad space to e-commerce merchants through cost-per-click bidding and interactive competitive activity.
