One of the issues with trademarks though is that-- with the exception of a few brands so globally prominent as to be basically protected in every possible arena-- trademarks are good for only a specific market. They can sell Dolch computers, but that doesn't prevent someone from selling Dolch blenders, as long as there's no attempt of consumer confusion. There's definitely an interesting argument there. "You mean this Quickfire Rapid covered in novelty caps is not a packet-analysis device?"
Also, it reminds me of how-- back in the day-- you could get all sorts of custom front-panel stickers for your PC to fit in that 1x1 inch logo opening old generic cases had. Many of the most popular designs were questionable from a trademark mindset-- Star Wars logos, processor, mobo, and video card maker logos, etc. Somehow people survived that era intact. Maybe it works with the above restriction-- the stickers themselves are presented in a way that doesn't cause customer confusion-- "replacement for touch-up/restoration of original PAC-xxx devices" -- and if someone slaps it on a PC and tries to sell it as a Dolch packet analyzer, that's their problem.
But what you are referring to refers only to name confusion. If there was a company called Dolch that also made non-mobile computers, they could have been sued for name confusion trademark infringement. If, however, there was a company called Dolch that made iced tea, they could not be sued because there is no possibility of confusion.
I know they survived that era intact. I mentioned the fact that the chance is very unlikely that you will get caught. If a tree falls in the forest and no one is there to hear it, regardless of whether or not it made a sound it has still fallen. The point is if you do get caught, you CAN and WILL be litigated. The problem is not name confusion. The problem is that you are profiting off of someone's logo. If it just said "Dolch." on a white background, there would be no issue. The fact that it is a direct and extremely accurate representational mimic of Dolch's logo in every respect except possibly size is an issue because regardless of whether you put it on a toaster or a packet analyzer, you are still profiting off of a logo that is protected by trademark and is not licensed by Dolch themselves or Azonix. If you made it say "Polch." or did a color swap, you would be on the edge of legality and could probably make a parody argument. In this case though, you are blatantly crossing the line by selling an unlicensed copy of a trademarked logo. If I were to sell a sticker with a Microsoft logo on it without asking them or obtaining a license, they would sue me.
As a final thought, I think I need to re-emphasize my stance. I would not do it, because it is illegal. However, I can almost say for sure that you will not be caught. If you do get caught though, (because this IS illegal) you will be punished. You can liken it to pirating music and decide whether or not the risk is too much for you and whether or not you want to do illegal things if you don't think you would get caught. Would you kill, lie to congress, or steal if you could be assured that you would not be caught? I wouldn't. This is the decision you have to make. I'm not going to stop you, though I hope you can see the point I am making. What I will suggest is that you change it in some way, i.e. a color swap, letter change or simply give them away. If you give them away, there is no problem. Then it's just free advertising for Azonix.
The problem is not the name. It is the entire logo which is protected by trademark/trade dress.
