"European Bilski: The Enlarged Board of Appeal of the EPO is looking for third-party input on four issues: 1. Is it only proper to exclude patents covering computer programs as such when explicitly claimed as a "computer program"? 2. Does a claim avoid the computer program as such exclusion by mentioning a computer or data storage medium? (If not, what technical effect is needed?) 3. Can a technical effect be non-physical? Is it sufficient if the physical entity is an unspecified computer? 4. Does the activity of programming a computer necessarily involve technical considerations? Input on the European questions are due by the end of April. http://www.epo.org/topics/news/2009/20090219.html."
