About us

Aim

IdeaNav helps inventors protect their ideas.

Who we are

IdeaNav was formed in 2007 and includes:

Patent Attorneys / Directors:
Anthony van Zantwijk (BSc(Civ)Eng, LLB, LLM(Tax)),

McLean Sibanda (MSc(Met)Eng, LLB, LLM-Commercial, PhD)

Paulo Lopes (MSc(Mech)Eng, LLB, HDip(Tax))

Trademark Attorney:
Taya Lombard (LLB)

Assistant: Lesley Mackell.

The company was spun out of Sibanda & Zantwijk Patent Attorneys (a firm specialising in intellectual property commercialisation).

Why S&Z?

  • In 2019 and 2020, S&Z was the #2 filer of South African provisional patents. And, in September 2021, S&Z became the #1 filer of South African patents.
  • S&Z patent attorneys used to work at one of South Africa’s biggest patent firms, Spoor and Fisher.
  • S&Z offer a complete range of intellectual property commercialisation services to clients including Anglo American, De Beers, Sasol, SARS and the SA Reserve Bank.

Pricing

We offer affordable patent and design services. To reduce cost, we also offer online patent, design and trademark filings.

We have discarded the industry-standard hourly-rate billing model and substituted it with a fixed, transparent pricing policy that inventors can budget on.

Independence and objectivity

To protect our independence and objectivity, IdeaNav refuses to accept or offer referral payments. All referrals are motivated by value to the inventor instead of relationships or reciprocity.

Software

We embrace online systems that reduce the cost to file and prosecute patents, trademarks and designs to grant. In this regard, we work closely with GlobalIPCo – a software company that develops: IP management systems (that we use to file and report on applications); and online filing systems (for which we are the exclusive South African agent).

Provisional Patent Online

Our online patent, trademark and design renewal system is also popular among multinational companies to reduce their cost of holding patents.
