One factor that is taken into account when determining likelihood of confusion is how sophisticated and knowledgeable the customers purchasing your goods or services are. The more sophisticated they are the less likely they would be to confuse conflicting trademarks. This is something that should be considered as you begin your new trademark application. If you are selling goods or services to professionals rather than the general public the sophistication may be considered high. If you are only selling to the general public, then it may be low. Ordinary purchasers are less likely to have as much specific knowledge in regards to what they are purchasing and a professional is more likely to discriminate between trademarks. The amount of attention a potential purchaser will pay when considering. Will they think about the various products available or just grab what they see first? Is this in an impulse purchase or would it involve careful consideration? These are all important questions when analyzing a conflicting mark this is for similar goods and services.
