I've seen many patent claim examples, and I've tried to write some myself, but each time it feels like I cannot adequately describe/articulate the invention to the level that is needed for the patent office, or that similar to the actual claim. How does one become "good" at this; is it just practice over and over? Also, I know law/writing is fluid, but any buzzwords or formulas that I could use in writing claims? Thanks.
One on-line resource is Patent Drafting for Beginners: A prelude to patent claim drafting at ipwatchdog. The "bible" of the mechanics of claim drafting is Faber on Mechanics of Patent Claim Drafting. It is about $500 on Amazon. You might find a version from a couple of years ago for sale somewhere. And Patent it Yourself would be a good start.
One exercise I did when I started was to try to write a claim for something simple that I was pretty sure was patented and then to look up the actual patent. My first try was on Apple's magnetic power cable/connector on Apple laptops.
As an aside, European claim drafting is very very different from U.S. claim drafting.
I am a layman too. I found Hal Milton's book to be a great resource:
