software law

(legal)Software may, under various circumstances and invarious countries, be restricted by patent or copyright orboth. Most commercial software is sold under some kind ofsoftware license.

A patent normally covers the design of something with afunction such as a machine or process. Copyright restrictsthe right to make and distribute copies of something writtenor recorded, such as a song or a book of recipies. Softwarehas both these aspects - it embodies functional design in thealgorithms and data structures it uses and it could also beconsidered as a recording which can be copied and "performed"(run).

"Look and feel" lawsuits attempt to monopolize well-knowncommand languages; some have succeeded. Copyrights oncommand languages enforce gratuitous incompatibility, closeopportunities for competition, and stifle incrementalimprovements.

Software patents are even more dangerous; they make everydesign decision in the development of a program carry a riskof a lawsuit, with draconian pretrial seizure. It isdifficult and expensive to find out whether the techniques youconsider using are patented; it is impossible to find outwhether they will be patented in the future.

The proper use of copyright is to prevent software piracy- unauthorised duplication of software. This is completelydifferent from copying the idea behind the program in the sameway that photocopying a book differs from writing another bookon the same subject.
