There is something wrong with calling something a cactus blank when someone else has gone through the effort to trademark it. I just had this hour long discussion with my patent attorney this afternoon and brought up this question with him. Sure, it may be the specific word is "original cactus blank", but the word original is just an adjective to emphasize Cactus blank. The tradmark protects the name cactus blank. Even if it is not federally liscenced as a trademark, it is still valid in every single state that one of his blanks was sold in. the trademark does not stop you from making a pen from a cactus skeleton, it only prevents the terming of that pen or blank as being Cactus. It also does not mean you can't say or type Cactus pen. You can say that all day long, but you say it in reference to what cactus pen is as per the trademark. The trademark is for business...he is protecting the name of a product, not an actual product. To change that to cactus slim would not hold up in court. You can call it a skeleton pen, or something else, but you can't call it a cactus pen because that takes away from the original trademark goal of protecting the name of his pen. If he lets you, then you can, but then he is giving up his trademark. As it stands, this thread is a lawsuit of huge numbers...like lets think small...I sell a ballpoint at $100 ea, and times 40, is $4000. Because of the trademark, if it were my trademark, I would argue that you sold $4000 under my name that I worked hard to build and protect. The lawyer fee's would be $2500 for me if I was the trademark person and the fee's would be equal or more for you <Ron> and so I would be up $1500 and you would be down $6500 or more.
Most importantly, it's all about respect. Have some respect for the person's that are trying to build a brand and spending the time protecting it.
