COMPUTER SCIENTISTS, WATCH OUT!

Apple and Lotus are trying to create a new form of legal monopoly: a copyright on a class of user interfaces.  These monopolies would cause serious problems for users and developers of computer software and systems.

Until two years ago, the law seemed clear: no one could restrict others from using a user interface; programmers were free to implement any interface they chose.  Imitating interfaces, sometimes with changes, was standard practice in the computer field.  The interfaces we know evolved gradually in this way; for example, the Macintosh user interface was developed over fifteen years at Stanford, SRI, Xerox and other places. Hundreds of students and researchers contributed to this effort, and no one has a right to own it all now.

Most computer companies, and nearly all computer users, are happy with this state of affairs.  Lotus and Apple say it does not offer "enough incentive" to develop their products, but they must have considered it "enough" when they made their decision to do so.  It seems they are not satisfied with the opportunity to continue to compete in the marketplace---not even with a head start.

If Lotus and Apple are permitted to make law through the courts, the precedent will hobble the software industry:

Express your opinion!  Reconsider your plans!  You can make a difference.
