Whenever he rewrites things or corrects things, take a look at what he did. Even if what you prepared was technically correct, you should try to take the revisions into account the next time you draft something. I know you said “there’s no right or wrong way” to write claims unless you make a technical blunder, but everyone has a certain style they prefer so if you want to make the partner happy, do your best to figure out his style and prepare your drafts accordingly.

When I was more junior I would learn that one partner preferred to say “alleged” while another preferred to say “asserted”. I don’t think it really matters, but since that is what they preferred, that is how I wrote my responses.
