IBM suing GRPN as BCYP is suing:
IBM has filed a lawsuit against Groupon (NASDAQ:GRPN), alleging that the daily deals website operator builds its business model using patents without authorization. "Groupon has refused to engage in any meaningful discussions about reaching a license agreement to end its infringement of IBM's patents," the firm's complaint said. Big Blue filed a similar lawsuit against Priceline (NASDAQ:PCLN) last year, accusing it of patent infringement in running its travel and dining websites.
All I say is IMHO and not to be construed as investment advice. I know nothing, as informed frequently by my wife.
