No, but you may use the superscript "TM".
Trademarks can be either registered ® or unregistered ™ (common law)
There is no record of a registered trademark for "Therapy Notes" in the Trademark Electronic Search System (TESS) at the US Patent and Trademark Office website. However that does not mean that it doesn't exist as an unregistered/common law trademark (™ as opposed to ®)
Trademark symbols include the registered trademark symbol (®), which is a capital "R" enclosed in a circle, indicating a registered trademark. The trademark symbol (™) is represented by a capital "T" and "M" in superscript, denoting an unregistered trademark. Additionally, the service mark symbol (℠) indicates a service mark, which is used similarly to trademarks but for services rather than goods.
Not necessarily, but if you fail to notify someone that the logo is registered, you can't bring suit against them for trademark violation. >>>> Actually, you can recover damages if you prove they had actual notice of the trademark registration, or you simply sue them under the laws protecting an unregistered trademark in state or federal courts.
You have some trademark protection if you use the mark in commerce (simply affixing it to goods or services which you sell), and registration is not strictly necessary to protect trademark rights. If you have an unregistered trademark, you can still sue another company for trademark infringement if they use your company name on their products or services, or use one which is similar enough that consumers are likely to be confused. However, if you file for registration (an experienced trademark attorney can make this much easier, as there are many pitfalls which can make TM registration difficult for laypersons), and the registration is granted, and you continue to use the trademark for 5 years without opposition, it becomes incontestable. Once a mark is incontestable, a defendant in a trademark infringement suit will not be able to argue that the trademark was ineligible for registration in the first place (such as by claiming your trademark is merely descriptive), even if it was. This means the defendant will have to hope that a court finds that there was no likelihood of confusion. In addition to federal trademark law, most states have laws governing unfair competition. You might also be able to sue another company for that, if you think they are appropriating your company's name, logo, or other means of identification.
If you control the trademark, yes.
Most trademarks are not written in one of the standard named fonts, but instead in a custom unnamed font created only for use in that trademark. Use by the trademark holder of any other font to write that trademark or of that font to write anything but that trademark can result in the termination of the trademark holder's rights to use the trademark and to use the courts to prevent others from inappropriately using it.
No; if it's registered, use the R, and if it's not, use the TM.
A trademark is protected for life as long as it is still in use.
What is the penalty and or fine for illel use of a trademark
It's not required to use the trademark or registered trademark symbols, and some designers feel it clutters the look of the packaging.
After.Chicago Manual of Style, 16th Edition. 8.152 - Trademarks...Although the symbols...(for registered and unregistered trademarks, respectively) often accompany trademark names on product packaging and in promotional material, there is no legal requirement to use these symbols, and they should be omitted wherever possible. (If one of these symbols must be used at the end of a product name, it should appear before any period, comma, or other mark of punctuation.) ...
