- Registered a trademark in Class 31, covering agricultural products and fruits, seeds, etc. When we initially sought registration of the mark, the Registrar refused the application because the mark was similar to a registered trademark. We successfully cancelled the registered trademark at the Board of Trademarks on the grounds that the registered mark was contrary to public order, good morality, and/or public policy.
- Registered and defended a trademark in Class 5. Following the registration of the trademark, a different applicant sought to register a similar trademark in a different class, Class 31. We succeeded in cancelling the mark in Class 31 at the Board of Trademarks on the grounds that the products of both parties were related and a similar trademark could cause confusion on the ownership and nature of the products.
- Appealed the Registrar’s denial of our client’s trademark application in Class 18. The Registrar held that the mark was not distinctive and was similar to a registered trademark. The Board of Trademarks reversed the decision of the Registrar.
- Opposed the registration of a trademark that was similar to the unregistered mark of our clients as applied to bicycles and accessories. The Registrar held that the client had a better right to the mark and that the opponents’ mark was similar to the trademark of the client.
