National Exams, 16-Mex-B8, Product Design and Development — December 2019, 3 hours, open-book examination (Casio or Sharp approved calculator only). Question 1 (40 marks) is mandatory; candidates choose 4 of the remaining 6 questions (15 marks each, only the first five questions as they appear in the answer book are marked, for a total of 100%). This is an essay/design-methodology paper with no numerical calculations. All seven questions are answered below for completeness.

An NDA is a legally binding contract that lets a company share confidential or proprietary information — design data, prototypes, supplier pricing, unfiled invention details — with a third party (a supplier, contractor or potential partner) for a defined purpose, while prohibiting that party from disclosing or using the information for anything else. It exists because modern product development almost always requires bringing outside parties into the design process before a patent can be filed or a product launched, and without a contractual protection the disclosing party would otherwise have no legal recourse if that information were leaked or exploited.
A patent grants the inventor (or the company the inventor assigns it to) a time-limited legal monopoly — the exclusive right to make, use and sell the invention — in exchange for publicly disclosing how it works. It exists to let a company recoup the R&D investment behind a genuine innovation by preventing competitors from simply copying it, and to create an asset that can itself be licensed or sold, converting an idea into a defensible, monetizable business asset.
Under the Canadian Patent Act, a patentable invention must satisfy three tests. It must be novel (new — not previously publicly disclosed anywhere in the world, subject to Canada's one-year grace period for the inventor's own prior disclosure); it must be useful (it must actually work and have a demonstrated practical utility, not be a purely theoretical idea); and it must be non-obvious (it must involve an inventive step that would not have been obvious to a person skilled in the relevant art at the time). It must also be patentable subject matter — a concrete invention (a product, process, machine or composition of matter), not an abstract idea, a scientific principle or a mere discovery.
Canada is a first-to-file jurisdiction (since the 1989 amendment to the Patent Act): the patent is awarded to whichever applicant files a complete application with the Canadian Intellectual Property Office first, regardless of who can show they conceived the idea earlier. This is why companies file promptly and treat internal disclosure of an unfiled invention as a competitive risk — delay, even for internal review, can cost the right to the patent entirely.
Once granted, a Canadian patent must be kept in force by paying annual maintenance (annuity) fees to CIPO; missing a payment can allow the patent to lapse. The patent right is also time-limited — it expires 20 years from the filing date, after which the invention enters the public domain and anyone may use it freely. Enforcement is the holder's own responsibility: CIPO does not police infringement, so the holder must monitor the market and pursue civil action against infringers if the exclusive right is to have any practical value.
