What do the circles C and P in the trademark symbol stand for respectively? (used to identify the year when the CD was made)

In China, TM on trademarks also has its special meaning. In fact, TM logo does not protect trademarks. Different from R. TM, it means that the trademark has been applied to the State Trademark Office, and the State Trademark Office has also issued a notice of acceptance, which has entered an objection period, thus preventing others from repeatedly applying, and also indicating that the existing trademark holders have the priority to use it.

Composition:

As a trademark, letters refer to the smallest writing unit of pinyin characters or phonetic symbols, including pinyin characters and foreign letters such as English letters and Latin letters.

The original Trademark Law classified a trademark consisting only of letters as word mark, while the newly revised Trademark Law of 200/kloc-0 regards letters as one of the constituent elements of a trademark, which is more practical and convenient for the trademark authorities to examine and approve trademark registration applications according to law.

Numbers, as the constituent elements of trademarks, are also the new provisions of the 200 1 trademark law. Numbers that constitute trademarks can be Arabic numerals or Chinese capital numerals.

As a three-dimensional mark that constitutes a trademark, it can also be called a three-dimensional mark, which has a length, a width and a height. The trademark logo composed of three-dimensional logo is called three-dimensional trademark, which is different from the trademark pattern we usually see on the plane, but appears in a three-dimensional material form.
