Case Highlights

Protecting intellectual property on the Web. Maria has successfully defended a controversial website in multiple lawsuits against it, dealing with complex intellectual property and free speech issues. In each case she forced the matter to be dropped, dismissed, or settled with the other side paying damages to her client.

Closing the page on an infringing publication. When a popular Utah magazine became the victim of copyright infringement and trade-secret theft, Maria stepped in to help, obtaining an injunction and damages and closing down the competing business within three months of filing the complaint.

Our Testimonials

What Our Clients Say

Maria Speth has been representing our companies for almost ten years. When people ask about my attorney, I always say that if I had 4 sets of new radial tires, I would wear out every one of them, and would still not find someone as talented and with as much integrity as Maria. I have used attorneys for more than 30 years and Jaburg Wilk is the only firm I trust with all of our legal needs. Their legal staff is creative and they all know how to think outside the box, never missing a trick…all a must when doing business on the Internet

Maria is a top-notch, exceptional attorney! If you are looking for a trademark/copyright/intellectual property attorney, look no further- Maria is sharp as a tack AND wonderful to work with- truly the best you will find. I also worked with Attorney Aaron Haar and Legal Assistant Debbie Gower- also top, top notch! Can't say enough positive things about the entire team.

Joann P.

We've been working with Maria Crimi Speth at Jaburg Wilk since around 2008. Through three different businesses we've owned and many challenges, they've always been in our corner, looking out for our best interests and there when we need them. Everything from legal disputes, starting and closing companies and buying and selling companies, they have been on our side through every one of them. Can't recommend them enough.

Maria is an exceptional attorney whose professionalism, expertise, and dedication truly stand out. She navigated my complex case with clarity and precision, always keeping me informed and explaining every detail in an easy-to-understand way. Her strategic thinking and attention to detail ensured no aspect was overlooked. What truly sets Maria apart is her diplomacy. Despite dealing with extremely difficult opposing counsel, she remained composed, respectful, and effective. Her ability to defuse tense situations and negotiate firmly yet tactfully was invaluable. Thanks to Maria’s hard work and unwavering dedication, I felt confident and supported throughout my legal journey. If you’re looking for a knowledgeable, skilled, and compassionate attorney who excels in even the most challenging circumstances, Maria is the one you want in your corner.
