The judgment of design patent infringement follows the principle of overall observation and judgment, so you said that the overall appearance of your product and the patented product are somewhat similar, but there are many differences in each view. In this case Whether these differences constitute legal differences must be judged based on the specific products and patents. As the party accused of infringement, your description must contain many subjective elements, so you can’t just listen to your description, but also look at the actual object. In addition, whether different colors and materials can constitute a difference in patent law depends on whether the patented design requires color protection. If so, then different colors will constitute a legal difference. As for the material, in most cases it won't make a difference.
