Copyright law was designed to allow the creators of a work of art to profit from it for a
limited time, has anything come out of copyright in the U.S. while you have been alive? Effectively with constant retroactive extensions to copyright law copyright has been made perpetual. Then you get to DRM and and EULAs. Copyright law gives specific rights to those who own the copyright and specific rights to those who own the individual copy. DRM and EULAs try to take away rights from the owner of the copy. EULAs typically try to say you don't even own the copy even though you recieved a bill of sale when you bought it.
Copyright has even been revised to the point where if I take an 19th century bible fix some spelling and punctuation errors I can then publish it with a current copyright under my own name. That is a travesty.
Why should a copyright owner by way of EULAs and DRM be able in essence to write their own laws?
Now on to software patents.
Software is already protected by copyright and should not gain a 2nd layer of protection. Either copyright or patent not both.
Like copyrights patents have been extended. Originally you had to patent a specific design. For example the classic mouse trap could have been patented and the more recent glue traps would not violate the patent because the method is entirely different. Now with software patents you patent the underlying concept. You patent the concept of mousetrap and ANY mouse trap violates the patent. You don't even have to provide an acutual design just a description of the concept.
Finally there does not seem to be anything built into patent law to penalize those who apply for patents that they should have known to be invalid. As an example of this the Microsoft FAT patent. Patent law currently allows you to apply for a patent even if a product implementing the patent has been on the market for up to 1 year. The FAT patent was for the DOS file system which had been on the market for 15-20 years by Microsoft when Microsoft applied for the patent. They used that patent to try to get payment from digital camera makers and flash card makers. Some paid up until someone fought it and won. But Microsoft was not penalized for a patent that violated a very basic part of patent law. A part that they were obligated to research and present to the patent office on application. Microsoft and/or their lawyer should have been penalized for this. But as far as I know the only penalty was the revocation of the patent. They didn't even have to give back the money they were paid for use of the (invalid) patent.
