Not content with letting Google have the last word in a social media slapfight over patents, Microsoft’s head of communications, Frank Shaw, took to Twitter yet again.

In a series of tweets, Shaw expressed his skepticism over Google’s assertion that it wants to reduce patent liability across the tech industry.

Hello again David Drummond. This is going to take a few tweets, so here we go. Let’s look at what Google does not dispute in their reply.Thu Aug 04 20:35:58 via SeesmicFrank X. Shaw

We offered Google the opportunity to bid with us to buy the Novell patents; they said no.Thu Aug 04 20:37:43 via SeesmicFrank X. Shaw

Why? BECAUSE they wanted to buy something that they could use to assert against someone else.Thu Aug 04 20:38:10 via SeesmicFrank X. Shaw

SO partnering with others & reducing patent liability across industry is not something they wanted to help doThu Aug 04 20:38:24 via SeesmicFrank X. Shaw

Google said that it hadn’t partnered with Microsoft on a bid for patents from Novell because a joint bid would not have protected the search giant in disputes with Microsoft. Microsoft, Apple, Oracle and EMC later won the Novell patents, but courts intervened and forced them to license the patents to the open source community.

Google also recently lost a play for patents from Nortel, after being outbid by a consortium of companies that included Microsoft and Apple. The Justice Department is now looking into the deal.
