I know this question is stupid but could anyone explain it.
What does (R) and (TM) mean in Intel brand name?
Intel(R) Core(TM) i7-2670QM
The same as when it appears in any other brand name or publication.
(R) or ® stands for Registered Trademark:
The registered trademark symbol (®) is a symbol that provides notice that the preceding word or symbol is a trademark or service mark that has been registered with a national trademark office. A trademark is a symbol, word, or words legally registered or established by use as representing a company or product
(TM) or ™ stands for Trademark:
A trademark, trade mark, or trade-mark is a recognizable sign, design, or expression which identifies products or services of a particular source from those of others, although trademarks used to identify services are usually called service marks. The trademark owner can be an individual, business organization, or any legal entity. A trademark may be located on a package, a label, a voucher, or on the product itself. For the sake of corporate identity, trademarks are being displayed on company buildings.
There are two different symbols are used to represent the trademark (TM) and (R). Where TM represents a trademark registration is under process whereas (R) means the trademark is a registered one.
