If you remember, VMBlog.com reported back on May 22, 2006, Stream Theory filed a lawsuit against Softricity, AppStream and Exent claiming the three companies were infringing on its U.S. patent number 6,453,334. The lawsuit, filed in the United States District Court for the Central District of California, was seeking damages and an injunction against Softricity, AppStream and Exent for their willful infringement of the patent.

Now, all this time later, CityWire is reporting that Stream Theory and Microsoft (as well as Citrix) have reached an agreement to settle the law suit.  They report:

Cambridge-based software design group Tadpole Technology has resolved its legal dispute with Microsoft and signed a confidential licensing agreement with the US giant.

The agreement grants Microsoft access to, and rights to use the patents of Tadpole's affiliates Endeavors Technologies Inc and SteamTheory Inc.

Microsoft and Tadpole have also agreed to withdraw and terminate all the outstanding legal proceedings each company had against the other.

Meanwhile Endeavors Technologies, on behalf of Tadpole Technology and its subsidiaries, have agreed that Citrix Systems can use both the patents granted and pending, and software developed by Endeavors and Stream Theory, in all its products.

Both agreements appear to bring an end a period of uncertainty for Tadpole which reached a head on 25 January when it revealed its results for the year to 30 September and said a difficult funding position was challenging the business.
