If the study shows a High Risk result, does that mean I can't register my trademark?

Not necessarily. A High Risk result means significant obstacles were identified, but the study's Strategic Recommendation section will explain your options. These might include modifying the mark to increase distinctiveness, narrowing your goods/services to avoid overlap with conflicting marks, seeking a consent agreement from an existing mark owner, or choosing an alternative mark. Many clients use the study to pivot early and avoid costly rejections down the road.
