现在看很多地方都分开来的。--在哪里看到他们是分开的？
通常来说IP包括patent和copyright，大多也把trademark算上，虽然说trademark这个
东西并不很intellectual。也有人把商业机密，knowhow这些东西也算进去。 但是一般
来说在谈到谁谁是IP lawyer，这个人是很大可能是做专利的或者至少做一部分专利相
关的业务。
switching to english, sorry. can't type fast in chinese...
tradmark/copyright lawyers often are general commercial lawyers and don't
really specialize on IP law. And they usually don't call themselves "IP
lawyers" (they may go "I'm a trademark lawyer") because this title as I
understand is still pretty much reserved
