[SIGCIS-Members] The impact of computer patents

Hi: I would be grateful for recommendations on books and papers containing thoughtful well-justified discussion of the likely or actual practical impact of the outcomes of the various attempts to patent the concept of a programmable computer (whether granted, refused or invalidated) on the early development of the computer industry, in the US and elsewhere. I have in mind the ENIAC and especially the Konrad Zuse patent cases, but am also interested in any others. (My searches for good references have been hampered by the proliferation of articles on software patenting - a topic which I am not trying to cover.) Cheers Brian Randell Sent from my iPhone
