FAQ

Frequent questions about IP in Ontario

What services do intellectual property lawyers in Ontario typically offer?

Intellectual property lawyers in Ontario typically offer these services:

  • Patent application drafting and prosecution
  • Trademark registration and opposition proceedings
  • Copyright protection and enforcement
  • IP litigation and dispute resolution
  • Trade secret protection strategies
  • IP licensing and commercialization agreements
  • IP portfolio management
  • Due diligence for business transactions

These services help businesses and individuals protect their creative and innovative assets throughout Ontario and beyond.

Patent attorney fees in Ontario typically range from $5,000 to $15,000+ for a complete patent application process. Costs vary based on:

  • Complexity of the invention
  • Attorney’s experience level
  • Number of claims included
  • Extent of prior art searches needed
  • Government filing fees (approximately $400-$800 CAD)

Many Ontario patent attorneys offer initial consultations at reduced rates or free of charge to discuss potential patent protection strategies.

Trademark lawyers can be found throughout the Toronto area, with many concentrated in the downtown financial district, particularly along Bay Street and University Avenue. You can find trademark lawyers through:

  1. intellectual-property.org’s directory of Toronto IP professionals
  2. The Law Society of Ontario’s referral service
  3. Innovation hubs like MaRS Discovery District
  4. Major law firms with offices in Toronto’s financial district
  5. Boutique IP firms in areas like Liberty Village and Yorkville

Many trademark lawyers in Toronto also serve surrounding areas like Mississauga, Markham, and Vaughan.

Copyright protection is important for Ontario businesses because it safeguards original creative works that often represent significant business assets. Copyright protection:

  1. Prevents unauthorized copying of content, software, and creative materials
  2. Establishes clear ownership rights for licensing and monetization
  3. Protects both economic rights (right to profit) and moral rights (right to attribution)
  4. Applies automatically upon creation, though registration provides additional benefits
  5. Lasts for the author’s lifetime plus 70 years in Canada

For Ontario’s thriving creative sectors, including film production in Toronto and digital media in Kitchener-Waterloo, copyright forms the legal foundation for business operations.

Startups in Waterloo Region should consult with an IP lawyer at these key stages:

1. Before publicly disclosing inventions or business ideas

2. When developing a brand name, logo, or product design

3. Before applying for funding or entering accelerator programs like those at Communitech

4. When negotiating contracts with developers, designers, or co-founders

5. Before entering partnerships or licensing discussions

6. When expanding beyond Ontario or Canada

Early consultation with IP lawyers helps Waterloo startups build protection strategies aligned with their business goals while avoiding costly mistakes.

For Ottawa tech companies, the main differences between patents and trade secrets are:

Patents:

  • Provide 20 years of exclusive rights
  • Require public disclosure of the invention
  • Involve formal application process through CIPO
  • Protect against independent creation by others
  • Cost more upfront but provide stronger protection

Trade Secrets:

  • Last indefinitely as long as secrecy is maintained
  • Require no registration or government fees
  • Demand internal confidentiality measures
  • Don’t protect against independent discovery
  • Can be lost if reverse engineered or leaked

Ottawa’s technology firms often use both strategies, patenting core technologies while maintaining peripheral innovations as trade secrets.
