These spots appear to be some type of fungal leaf spot. Generally, leaf spot will not impact the health of your plant.  You may want to consider removing the affected leaves and branches. Raking away infected leaves in the fall will help prevent the spread. Remember, fungus thrives in moist environments, so minimizing water on foliage and maximizing airflow will go a long way!
