You're right about the grammar. No company with improper grammar should get a patent. In fact, they should probably do away with inventive step criteria and replace it with grammar. Delist them while we're at it, cause grammar is more important than the financial health of a company. Too bad this is still a profitable installation company in an emerging industry that is just scratching the surface (with or without cell). This elevator is only going up, good luck trying to get it to go the other way. Oh wait, the grammar just ruins everything! I just fell off my chair again laughing.
