Tax code patents
As an inventor with a few patents to my name, I wrestle with chemistry and physics in attempts to improve on industrial processes and measurement techniques. I hope these will be commercially profitable and redound in a small way to the benefit of mankind. That is the legal premise of patent law: inventors are incentivized by the patent's grant of a 20-year monopoly on commercial exploitation of the invention in exchange for disclosing the principles of the invention publicly. In this manner the "teaching" of the invention eventually ends up in the public domain for the public good instead of being held indefinitely as trade secret. Patents make Western society dynamic, and Islamist extremists see destruction of the intellectual property system as a key battleground in the war of civilizations.
