You must act promptly to ensure that you are not infringing the trademark. The rights of the accuser to their trademark, as well as your rights to your trademark, must be investigated to determine who has superior rights, and in which geographic region those rights are superior. The similarity of the trademarks, the strength of the trademarks, the goods or services sold under the trademarks, and other factors must be reviewed to determine whether a likelihood of confusion exists. If there is no likelihood of confusion or if you have superior rights in the relevant geographic region, we can inform the accuser of this fact, and you can continue your activities with relative safety (but no guarantee that you will not be sued). If infringement appears likely, then steps can be taken to mitigate your liability for trademark infringement, including discontinuing use of the infringing trademark, negotiating a coexistence agreement, etc.
