A China filing starts with a clearance search in each class you care about. Chinese examiners compare marks within sub-classes (类似群), so the search and the list of goods follow the Chinese sub-class system. Picking items from the standard Chinese list avoids refusals over wording.
What I check before filing
- Identical and similar earlier marks in the relevant sub-classes, with a risk rating for each.
- Whether the word describes the product too directly to be registered on its own.
- Which versions to file: the word, the logo, a combined mark, and the Chinese name.
- Which goods earn money now, which are planned, and which are purely defensive.
What to file first
Budget usually decides the order. Core classes for the products you sell or make now come first. Classes for planned products and defensive items follow in a second batch. A short, attractive word is often the hardest to register, so I usually suggest filing a combined mark or the full name first and treating the short word as a separate decision.
After filing
The application is examined, and if approved it is published. During publication others may oppose it. If there is no opposition, the mark is registered. If the examiner refuses some items, a review can be requested within the time limit on the refusal notice.
