International Business Machines Corp () is suing coupon site Group Inc () for US$167mln over what it says are infringements of its patents regarding e-commerce technology.
Two of the patents involved in the lawsuit are relatively old intellectual properties (IPs) that have origins in the pre-internet Prodigy online service that was distributed by from the late 1970s onwards.
Commenting on the proceedings, John Desmarais, a lawyer for said, “The new kid on the block  refuses to take responsibility for the technology it’s using” and that “Most big companies have taken licenses to these patents. Groupon has not.”
On the other side, Groupon lawyer David Hadden argued that the case was not valid as the patents don’t cover the worldwide web, because IBM did not invent it.
Hadden accused IBM of using its patents to extract money from other companies, saying the IT firm used its “huge stock of patents as a club to get money from other companies.”
IP licensing is a high-margin business for IBM, who has been winning the largest number of patents in the US every year for the last 25 years, however, it only comprises around 2% of total revenue.
In mid-morning trading Tuesday, IBM shares were down 0.9% at US$144, while Groupon shares were up 0.3% at US$4.7.
