converse 鞋款問題 : R 與 TM

converse all star
通常鞋後面個底部都有 logo
粒星下面會有 R(圈住) 或者 TM
其實兩個都係註冊商標
咁兩者有乜分別?
R 主要在運動家同旺角某幾間出面鞋舖出現
TM 則出現在一些小型舖頭

多謝解答

TM- A trademark is either a word, phrase, symbol, or design, or combination of words, phrases, symbols, or designs which identifies and distinguishes the source of the goods or services of one party from those of others.

A trademark is often a company's most valuable asset, requiring the protection of a federal trademark registration.

I think circle R is either patent or copyright, not sure about this one.
A patent for an invention is the grant of a property right to the inventor, issued by the Patent and Trademark Office.

Copyright is defined as the exclusive right of a creator to reproduce, prepare derivative works, distribute, perform, display, sell, lend or rent their creations.

不過我都想問: R 係真定 TM 係真定係兩種都係真 Converse?
