If an approved trademark contains a pattern, it cannot be changed at will. Just zoom in and out at the same time according to the original proportion. If it is necessary to change the registered trademark, it may apply for registration separately. R cannot be circled before approval. You can also use old and new trademarks at the same time. The old trademark is R, the new trademark is not R, and the new trademark is registered before R. After a transitional period, only the new trademark is used to replace the old trademark.
