PKWare Files a Patent Application for Secure .zip

prostoalex writes "The battle of ZIP formats might intensify as PKWare filed an application with USPTO to obtain a patent on its Secure Zip technology, which pretty much involves archiving with strong cryptography. If the patent gets granted, PKWare will license its algorithms for other software manufacturers. A representative of Aladdin Systems summed it up: "The good thing about the .zip file format was that you knew you could send it to everyone. Now that's getting broke.""
