Shift Law is a small entrepreneurial law firm that has in-depth experience with handling high-profile cases. They’re also significantly fast in patent prosecutions and have the highest satisfaction rate in our list.

What sets them apart is their approach to strategic guidance. Their team of professionals has a reputation for giving smart suggestions that lead most cases to success.

As a small firm themselves, the company also caters to small business and individuals. In fact, as mentioned, they can also handle cases with a success that’s difficult to emulate.

Although relatively young at 7 years old, the firm already has significant expertise in IP litigation and has even managed to score recognition in prestigious lists.

One example is the list of 2022 Best Lawyers, where John Simpson (the firm’s principal founder and trademark agent) was named. Working alongside him are other IP lawyers who specialize mostly in Information Technology (IT) and branding protection.

In terms of pricing, they offer bundled discounts for small businesses seeking trademark registration. Overall, their fees are fair as services go, according to past clients.

Pros

  • Experience in high-profile cases
  • High success rate
  • Expertise in copyright infringement cases
  • Specializes in the commercialization of IP and IT
  • Experience with both small business and big corporations
  • Featured in the Best Lawyers 2022 list
  • Bundled discounts for small businesses

Cons

  • Doesn’t offer complimentary consultations
  • Little experience in patents in particular

UIPatent are certified experts when it comes to patentability of inventions, patent infringement, and patent validity. Basically, they specialize in all things patent, making them an exceptional choice in this field.

Unlike other law firms, the team of professionals in this firm has remarkably diverse technical backgrounds. They specialize in engineering disciplines to pharmaceuticals, software, energy, and even aerospace.

This can make them a good choice if you need more versatile patent lawyers… or ones with experience in the aforementioned fields.

On top of that, they’ve also handled various types of clients from universities and individual inventors to large corporations. If you add their decade of experience, we can say that they’ve mastered the field of patents.

In line with patents, the firm has the most comprehensive approach to all patentability matters. Even past clients still praise them today with the successful results they were able to deliver.

We love that they’re transparent with their fees but the charges do tend to go high depending on the case’s nature. To make up for this, we see the free consultation as a great bonus.

  • Experts in patentability, patent infringement, and patent validity
  • Specializes in diverse technical disciplines
  • Experience with a wide range of clients
  • Transparent fees for all services

Unlike the other entries, Sander Law is a small practice with Jennifer Sander, a freelance patent attorney. While that means that there isn’t a team of professionals here, she’s still one of the best in the league.

One of the best advantages of hiring her is her length of experience. She’s a licensed lawyer, a registered patent agent, and a registered trademark agent who’s been in the business for 10 years.

She specializes in various areas of IP law including registering IP rights, IP assignments & licenses, and IP enforcement. It’s not a practice solely focused on patents, but we can infer that her track record speaks for itself.

With perfect ratings on Google Reviews, she’s one of the highest-rated lawyers in this list with a solid success rate. The best part is, she offers flat rate fees for certain services, making the entire process cost effective for clients. 

Another edge that you can get by hiring her is flexibility in time and working process. You can hire her by the hour or contract her for part-time or long-term projects.

Lastly, she specializes in mechanical, electrical & computer related inventions. You might want to consider a consultation with her if your case falls under these categories.

Pros

  • Specializes in mechanical, electrical & computer related inventions
  • Lawyer and patent agent
  • 10 years of experience
  • Offers flat rates on most services
  • Flexible work structure and schedule
  • High success rate

Cons

  • Not backed by a team of legal professionals

Ridout & Maybee LLP, in our opinion, is one of the best when it comes to having a robust track record. Other than that, they have a large team of industry professionals and have been leading the IP game since 1893.

As they’ve been in the business for 126 years, it’s not surprising that they’ve already handled 190,000 Canadian patents. With that amount of experience, you can tell they’re more than seasoned in the area of IP laws.

As per specialization, their legal services are tailored to specific industry sectors, though they do handle almost any case imaginable. Still, to set it fair and straight, we think they work best for IT, science, and engineering-related cases.

Were also impressed with their record of 56,000 international clients. Other firms have yet to achieve this (considering the years of service) so they might just be the best choice for foreign businesses.

As a final note, the prices are normal for the city and nothing too ridiculous for what they do. They are also very hands-on with the clients, leading to favorable success rates over the years.

Pros

  • 126 years in services
  • Handled 190,000 Canadian patents
  • Worked with 56,000 international clients
  • Solid technical background in diverse sectors
  • Specializes in IT, science, and engineering-related patents
  • Competitive rates

Cons

  • Certain services can be expensive

Very professional group. Very easy to communicate and work with. Helped us to file a provisional patent application. Although our system is a high-tech system, it was very easy to communicate with them and they understood all aspects of our design perfectly. – Younes Sadat-Nejad
