Class 42: Scientific & Technology Services trademarks

Services class

Class 42 covers software as a service and technology services - the class where most modern startups actually belong. If customers use your software in a browser instead of downloading it, you're here, not Class 9. That distinction trips up more filings than any other.

What belongs here

SaaS platforms, cloud computing, software development for others, AI services, scientific research, web hosting.

Often filed alongside

Class 9 for any downloadable app, Class 35 if the platform is really a marketplace.
