IPOPHL Patent Agent common mistakes
IPOPHL Patent Agent · Understand the traps and how to avoid them.
Treating an industrial design as a patent in miniature and analyzing novelty/grace period and term the same way as for an invention, or forgetting that a design protects appearance (lines, contours, colors, shape, texture, ornamentation) rather than technical function.
The exam's design questions reuse patent vocabulary (novelty, prior art, priority), so candidates transfer invention rules mechanically and miss design-specific doctrine such as the requirement of a single design per application, the prohibition on purely functional features, and the different term and renewal.
What to do instead
Before answering any design item, state in one line what is protected (appearance) and what is excluded (function, technical features). Build a comparison table of term, renewal, grace period, and multiple-design rules for invention, utility model, and design, and drill until you can reproduce it from memory.
Applying a single 12-month grace period to every IP right, or assuming the grace period rescues a disclosure that was made through a printed publication abroad or through commercial use, when the applicable rule differs by right and by the nature of the disclosure.
The grace period appears in several domains with different lengths and conditions, and reviewers often memorize one number. The conditions for what counts as a qualifying disclosure (for example, disclosure by the inventor, at an official exhibition, or in a learned-society publication) get collapsed into 'any disclosure within the period.'
What to do instead
Write out the grace-period rule separately for invention/utility model and for design, including the qualifying categories of disclosure and who must have made the disclosure. For each practice question, identify which right is at issue before recalling the number.
Confusing the Utility Model with the Invention in scope and examination: assuming a utility model can cover processes, methods, or chemical compositions, or assuming it receives the same substantive examination as an invention.
The two share most filing mechanics, so candidates default to invention rules. The utility model's restriction to products, its lower inventive-step threshold, and its typically registration-style (non-substantive or limited) examination are easy to blur when the question is framed around filing procedure.
What to do instead
Memorize the utility model as a product-only right with a lower inventive step and a shorter term. Practice classifying a list of subject matter (a process, a device, a composition, a circuit layout) as eligible or ineligible for a utility model, and be able to state what kind of examination each right receives.
Mishandling the PCT timeline: mixing up the 12-month priority period, the 16-month transmittal to the International Bureau, the 18-month publication, the 22-month and 28-month national-phase deadlines, and the 30-month extended deadline, or applying the wrong deadline to the wrong event.
The PCT is a chain of milestones, and candidates memorize the numbers as a list without anchoring each to the event that triggers it. Under exam pressure, adjacent numbers get swapped, especially 22/28/30 months and 16/18 months.
What to do instead
Draw the PCT timeline once, from filing through priority, transmittal, international publication, demand, and national phase, and label each milestone with its month and the event it is measured from. Then answer timeline questions by locating the milestone on your own diagram rather than recalling a bare number.
Treating the international application as a single worldwide patent and assuming the International Bureau or the receiving Office grants protection, instead of recognizing that the PCT only defers and coordinates national/regional prosecution.
The phrase 'international application' suggests a unitary grant. Candidates who have not internalized the PCT's function conflate the international phase with the national phase and answer questions about 'the international patent' as if it existed.
What to do instead
State the PCT's purpose in one sentence: it buys time and creates a common filing date and search, while each designated State decides grant under its own law. For every PCT question, ask whether it concerns the international phase or the national phase before answering.
Running a patent search that stops at keyword matching in titles and abstracts, without building a classification-based strategy, without synonyms and truncation, and without documenting the search history.
Keyword search feels intuitive and produces quick hits, so candidates skip the classification step and the iterative refinement that a defensible search requires. They also underestimate how terminology shifts across jurisdictions and languages.
What to do instead
Practice a fixed search protocol: define the invention's concept, map it to the relevant classification, combine classification with keyword sets using synonyms, truncation, and proximity operators, then review and refine. Record the query strings and date of search, because exam items on search methodology reward a documented, reproducible strategy.
Answering analytics and examination-guideline questions with general patent-law principles while ignoring the specific office guideline that governs the point, such as how inventive step is assessed, how claims are construed, or what the examination sequence requires.
The substantive law and the examination guidelines overlap in wording, so candidates answer from first principles and miss the procedural or methodological detail the item is testing. Guideline questions often hinge on the order of steps or the standard applied, not the outcome.
What to do instead
Study the examination guidelines as a procedure: the sequence of examination, the standard for each ground, and the form of objection. When a question cites a guideline, answer with the guideline's method (for example, problem-and-solution or a structured inventive-step test) rather than a general conclusion.
Confusing the legal nature of the instruments in technology transfer: treating a license as an assignment, ignoring whether a license is exclusive or non-exclusive and whether it is recorded, or overlooking the registration requirement for the transfer to affect third parties.
Assignment and license are often discussed together, and both transfer economic value, so the distinction blurs. Candidates also forget that recordal or registration can be a condition for enforceability against third parties rather than a mere formality.
What to do instead
Build a two-column comparison of assignment versus license: what right passes, whether it is exclusive, term, and the effect of recordal. For each scenario, first identify which instrument is being used, then apply the recordal consequence separately.
Treating mediation and adjudication as interchangeable dispute-resolution routes, or assuming a mediation settlement is automatically enforceable as a judgment without the required step to give it effect.
Both are dispute-resolution mechanisms within the IP adjudication system, and candidates answer questions about jurisdiction, procedure, and enforceability using the litigation model for mediation or the reverse.
What to do instead
For each dispute question, identify the forum and the nature of the outcome (adjudicated decision versus mediated settlement), then state the procedural consequence of each. Know which body has jurisdiction over which type of IP dispute and what is required to make a settlement enforceable.
Conflating the criteria and scope of the different registrable marks and rights: applying trademark distinctiveness analysis to copyright works, or confusing what a geographical indication protects and who may use it with the rules for a certification or collective mark.
These domains share concepts such as distinctiveness, ownership, and infringement, so candidates reuse one analytical framework across them. Copyright's originality and fixation requirements and the GI's link between product and place get lost in the overlap.
What to do instead
Maintain a one-page matrix of each right's subject matter, eligibility test, term, and infringement standard. When a question spans domains, name the right first, then apply only that right's test, and check the GI answer against the product-place link and authorized-user rules before selecting.
