Returning to CoH after two years...
Correct, those are Invention Origin (IO) Enhancements.
Single Origin (SO) Enhancements you buy from vendors in the game or gain as drops. The same goes for Dual Origin (DO) Enhancements.
A new term you may hear or come across is SBEs (Store Bought Enhancements.) These are purchased from the Paragon Market with Paragon Points, are store counterparts to similarly named IO Sets like Mako's Bite and such but ARE NOT Invention Origin. You can slot these regardless as to whether you can use IOs or not. They are account bound so you cannot auction or trade them.
Another new term you may hear or come across is ATOs (Architype Origin Enhancements), these are typically gained from Super Packs which are purchased from the Paragon Market. but ARE NOT Invention Origin. You can slot these regardless as to whether you can use IOs or not. These are not account bound so you CAN auction and trade these. (Edit: Once a Catalyst has been used on and ATO to upgrade it to a Purple version of the ATO is can no longer be traded or auctioned.)
Also, people will incorrectly refer to ATOs as ATIOs, this tends to lead to confusion as some will assume that it follows the same rules as the Invention Origin Enhancements.
Alright, then I understand now. Thanks for link and info about the new terms - nice to know when I come across it.
For now I'm just going to buy some new time and play the full game, so I can catch up with all the new stuff! Thanks again guys, hope to see you around.
Welcome back to the game and enjoy!
Correct, those are IOs. They are generic IOs, not Set IOs, but still IOs, and they won't work with out a license ($2 per moth) or a VIP membership or Tier 7.
SOs are the ones that say Mutant or Technology or some other origin. Those will work for any level of free play.

EDIT: not seeing a good picture of just SOs, but here's a picture of various enhancements. Left to right they are Dual Origin, Training, Single Origin and then Dual Origin again. You can tell by the border.
