The only company claiming WAP "ownership" that I am aware of is Geoworks,
Inc. in Alameda, California.

They claim that their patents (US Patent #5,327,529
http://www.patents.ibm.com/details?&pn=US05327529__ and Japanese Patent No.
2,794,339 ) "Process of designing user's interfaces for application
programs" covers the "do" keyword in WAP's WML. The patents cover some of
the features of their FlexUI development environment for the GEOS windowed
operating system. It is interesting to note that mobile devices are not
mentioned anywhere in the 42 pages of the patent, and the patent cites no
non-patent prior art.

I communicated with Geoworks cheif technical officer, Adam de Boor, in
January 2000 and he confirmed that Geoworks has no patent claims in Europe.

Geoworks white paper outlining their claims to WML can be found here -

Additional articles about Geoworks and their WAP claims can be found here -
