Microsoft was on Wednesday ordered to modify the main versions of its Word program for creating documents and pay $240m for infringing on a patent held by a small Toronto company called i4i.

The ruling by a federal judge in Texas affirmed a jury decision in May, rejecting Microsoft’s attempts to set i4i’s complaint aside on numerous grounds. Among other claims, Microsoft said the judge in the original case had erred by refusing to let it tell the jury that federal examiners were reconsidering the legitimacy of the patent.
