The team at BSTZ are very professional and helpful. They are very thorough and will be there to help you with whatever you need. They are very knowledgeable in their field and have the experience to help with any issues you have. I have never had any issues with BSTZ and I would highly recommend them to anyone looking for IP legal representation. The only downside is that there is a delay with filing a case. I believe it takes at least four to six weeks to file a case with BSTZ. It's worth the wait. They are very diligent and will ensure that you have the best possible case. They are also very affordable. I have had no issues with BSTZ and I would recommend them to anyone looking for IP legal representation. I have had a few issues with the USPTO and BSTZ has taken care of them. I would recommend BSTZ to anyone looking for IP legal representation.
