I've had the pleasure to work with Mark Emde and the Block45 Legal team over the last year and they have been incredibly knowledgeable and helpful with several of our cases. Mark helped us to get through two trademark applications and was very thorough in his submittal and communicated with us throughout the whole process. He was also always willing to teach and explain the risk, limitations and gray areas of the law and willing to seek help and expertise when he wasn't sure in an answer. I've really appreciated the opportunity to work with Mark and the Block45 Legal team. They've been fantastic!

If you have trademark or patent requirements, look no further than connecting with Mark Emde. Mark makes his clients feel protected and safe, no matter what happens, throughout the whole cumbersome process. He is prompt, professional, and passionate about what he does - which is exactly the type of person I want to work with. Appreciate you Mark and the Block45 legal team.

Block45 (Clement Hayes/Mark Emde, et al) patent attorneys are by far the finest I have EVER worked with in my 50 years of experience! As the original inventor of wireless In Ear Monitors and the personal audio and ear bud industry that spun off of them, I have seen all sides of Intellectual Property attorneys and agents in all aspects from searching, filing and maintenance to portfolio management and litigation and I have to say these guys are simply THE BEST I HAVE EVER HAD THE PRIVILEGE OF WORKING WITH - both legally and as individuals. They literally saved my lifelong IP portfolio and heritage as well as my company from dilution, corporate takeover, infringement and malfeasance and opened the door for tripling the scope of our future IP. They have earned my undying allegiance and faith and are the reason behind our ability to enable AC/DC’s historic 2024 tour of Europe as well as their upcoming tour of the US in 2025! If you or your firm deal in IP, you can’t do better that Block45 Legal!
