Excellent legal counsel
As in-house counsel, I hired Clement and team to assist with several of our IP and related issues that are outside of my expertise. They are all very knowledgeable and professional while always balancing their advice with appropriate business considerations. Clement is remarkably responsive and accessible which I appreciate as when issues arise in the business world they often require immediate attention. Highly recommend.

The team at Block45 Legal is extremely knowledgable. They came up with a legal strategy for my case that I would not have ever considered. I did not use their corporate arm but they still offered support and advise throughout my case. Thank you Clement and all of Block45.

I love Block45 legal!
I love Block45 legal! Owning internet companies comes with a dynamic and modern set of challenges that most law firms do not have the talent to handle. Block45 not only understood the needs of my business model but they tackled them head-on with modern advice and top-notch legal strategies. They are a valuable asset to my business.

Great to work with!
I have worked with Clement on several major legal issues. He is extremely professional, prompt, and thorough. He worked with me to find ways to save on the bill as well and seemed to always have my interests in mind, even when it cost him fees. I highly recommend Clement for any small business or startup needs your company might have.

Clement has been with our startup business since the beginning and has lead us in filing Patents, writing Operating Agreements and many other legal docs. He is responsive and cares about the business. I have already recommended him multiple times and will continue to do so!

Clement Hayes with Block 45 Legal
We work with Clement at PurePressure and he has really been helpful for us through multiple legal projects, including patents (his speciality), retailer agreements, operating agreements + restructuring, and much more. We'd recommend him and Block 45 to anyone.

I'll hire this attorney again
Based on a positive recommendation from a corp exec who has hired Clement Hayes in the past, I employed Clement and we have worked closely together now for over a year on a Trademark infringement case. Even though I am based in California, Clement has been great about keeping me timely informed regarding my case. He is thorough and efficient, and the legal docs he has prepared have been well researched and very effective in moving my case forward. His fees are fair, and actually conservative compared to West Coast rates.

Uniquely skilled and talented attorney with a passion for progress
Clement's background in medicine and biochemistry are complementary to his expertise as a patent attorney. I have hired Clement specifically to protect and assist in developing intellectual property in the highly regulated and complex world of medical cannabis and cannabinoid therapies. His knowledge of current state and federal policies and the most up-to-date science available from the study of cannabinoids has been invaluable to our efforts. More than just an astute observer within our team, Clement is a contributing participant to all that we do. He has provided insightful commentary to our project allowing us to consider the requirements for creating a solid patent and maximizing protections of intellectual property that we are developing. His skills and understanding of multiple scientific disciplines has made communication and collaboration with our scientific staff and medical professionals smooth and flawless. I will actively seek opportunities to engage Clement further in future endeavors, and I give him my highest recommendation. I am also available to provide witness or further commentary to anyone interested in his services.

Clement review
Last year, my family and I encountered a very complex and messy situation that fell in our laps unexpectedly following the shut down of a company I used to work for. Although Clement was well versed in the matter of my case, he introduced me to an attorney on his team that handled many cases just like mine with winning favorable outcomes for the client. Although Clement did not personally represent me, he still took his personal time, of which he was not getting paid for, to call me weekly and offer to listen and lend support to me and my family in what was a very stressful and confusing time in our lives. Clement was ALWAYS available for my questions and if he couldn't answer them right away, he got back to me very quickly with the answers. His colleague got us a favorable outcome in the case and I would use absolutely call Clement and his team should the need for legal counsel present itself again. He truly cares about his clients and treated our case as if it were his own throughout the entire process. Thanks again Clement and Block 45 Legal, keep up the great work!

Great Trademark and Copyright Attorney in Denver.
Wow! What a great guy and terrific Attorney. We could not be more pleased with all the work that he has done for our company. We are currently involved in several projects with Clement, which unfortunately, we cannot be specific about at this time. Regardless, we feel that he is very capable and definitely recommend him to others. Marty, Aspen, Colorado

An insightful legal partner who focuses on your goals and works hard to help you succeed
Clement has been instrumental in helping my small business navigate a complex legal landscape and position for success. His consultative approach enabled him to address my specific legal concerns and much more. I initially retained Clement to help secure a trademark for my brand, which he easily supported. After consulting with me, Clement was able to offer guidance on patents, intellectual property and general business matters. His breadth of knowledge and experience were evident from day one and he has become a trusted voice and critical partner in my business' success. Clement is engaging, proactive and detailed in his work. He understands me and my business, and I have come to trust his counsel. I highly recommend Clement for anyone in need of a trusted legal partner in general business matters, patents & trademarks, and everything in between.

Great critical thinker
I have had the pleasure of working with Clement on various intellectual property matters. He works directly with clients to provide a thoughtful deep-dive analysis of the issues and presents his conclusions in a manner that is precise and easy to comprehend. If you are looking for guidance through patents, trademarks or licensing, you would be remiss not to consider Clement.

Professional & Approachable
Clement is very down-to-earth and easy to work with. He is great at explaining things in a way that makes legal language much easier to understand. The trademark process was very smooth and we are beginning work on a patent. Highly recommend working with Clement! In fact I already referred my best friends to him.
