Patents are renewable. You just renew.
The timing of all of them has to do with the expected use.
Copyright is a unique work, a song, a novel, a painting, so it has the longest protection.
Patent is for a process or product, theory being once you've made your money off it, there should be an opportunity for it to enter the public domain and become ubiquitous, benefiting all. But you can renew if you are still producing the product or using that proprietary process.
Trademarks are any identifying characteristic of your brand, often common things like words, phrases, colors, shapes; so if you don't use it, you lost it pretty fast. The thinking being other people should be allowed to use common elements, acronyms, etc., so we shouldn't allow one business to monopolize the use of common things.
Excellent answer. Only service mark was missing.
