§Text Passage
1The fruit of design is not only the artefact but also intangible intellectual property. Common categories in Hong Kong fall into four: patents protect new inventions or technical solutions, such as a novel mechanism or an energy-saving method; trademarks protect a brand's name and marks so consumers can identify the source; copyright protects original works, such as manual illustrations, software and advertising copy; registered designs protect a product's shape, pattern or colour. The four protect different objects — complementary, not overlapping.
2The ways the rights arise differ. Patents and registered designs generally require application and registration with the authorities, protected for a limited term once approved, after which the technology or appearance becomes free for the public; copyright arises automatically when an original work is created, without registration; a registered trademark enjoys stronger protection, though unregistered marks can accumulate some rights through use. Designers must know how to protect their own results — and respect the rights of others.
3Exam integration starts with decoding the stem. The keys of a scenario question hide in four kinds of words — users, setting, functions and constraints; circle them and answer one by one. If the question involves a smart product, first draw the input-processing-output diagram and judge open-loop or closed-loop; if it involves materials, match properties to purposes; if it involves value judgements such as sustainability and universal design, show how the requirements land in the specification.
4The answering frame compresses into five steps: decode and circle the keys; model the system in a block diagram; list the specification item by item; unfold the scheme tied to the scenario; evaluate against the specification. Write one step per paragraph, linked by sequence words; combine words and sketches, annotating every drawing. Outline first, then write, then re-check the keys before finishing, so that every requirement finds its answer.
5Three common mark-losers: a scheme that ignores its own specification, listing targets the design never answers; sketches without explanation, leaving the examiner to guess the ideas; and forgotten users — functions discussed without users or settings. The remedy is a habit: find a match for every specification item, add a note to every sketch, mention users in every scheme, and let all your learning show whole in the answer.

3Step by step Steps
- Step 1: An overview of the four kinds of intellectual propertyIntellectual property protects the intangible results of design, and four common kinds must be told apart: patents protect inventions — how a technical solution works; trademarks protect brands — names and marks that identify the source; copyright protects original works such as illustrations, software and copy; registered designs protect appearance — a product's shape, pattern and colour. For example, a newly designed folding umbrella may patent its novel rib structure, hold copyright in its canopy print, own a trademark in its logo and register its distinctive form as a design — four kinds, four corners.
- Step 2: How the four rights arise and how long they lastThe rights arise in two ways: patents and registered designs must be applied for and registered with the authorities, protected for a limited term once approved, after which the technology or appearance is free for the public; copyright arises automatically on creation, needing no registration; a registered trademark gains stronger protection, though unregistered marks can build some rights through use. For example, a company inventing a power-saving circuit should file for a patent promptly, lest another party register first and bar the original inventor from using its own invention.
- Step 3: Respecting intellectual property as professional conductDesigners protect their own rights and respect others': never copy another's appearance, never steal images or copy, never imitate a similar trademark to confuse consumers. Learn the thinking behind existing products without lifting their form; cite sources or obtain licences for quoted images and data. For example, copying an online illustration into a school project infringes copyright; redrawing it yourself or using licensed material is the proper path.
- Step 4: Decoding scenario questionsBegin by circling the keys, which come in four kinds: users (who), setting (where), functions (what it must do) and constraints (what must not be crossed). Answer each one; a missed key is a missed mark. For smart products, draw the block diagram first and judge open-loop or closed-loop; for materials, match properties to purposes; for sustainability or universal design, write the demands into the specification. Take a medicine-box reminder for elders as an example: elders are the users, the box the carrier, reminding the function — so the specification lists large buttons, large print and a loud alert.
- Step 5: Operating the five-step answering frameThe frame runs: decode and circle the keys; model the system in a block diagram; list the specification item by item; unfold the scheme tied to the scenario; evaluate against the specification. One step per paragraph linked by sequence words; every sketch annotated with the idea and how it works; every specification item answered by the scheme. For example, in a smart-bin question, fix input and output in the diagram, list targets such as auto-opening and full-load alerts, then answer item by item with an infrared sensor and a weight sensor — beginning and end joined.
- Step 6: Common mark-losers and remediesAvoid the three great mark-losers: a scheme that drifts from its own specification; sketches without explanation, which the examiner cannot mark; forgotten users and settings, where fine functions still miss the point. The remedies are three habits: find a match for every specification item, add a note to every sketch, mention users in every scheme. For example, if the specification promises one-handed operation but the scheme only discusses looks, the marker finds nothing to credit; one line — grip-side buttons within one-hand reach — secures the mark.
- Step 7: Revision strategy for the examinationRevise around projects: for each, write a four-part digest — process, materials, systems, values — then set yourself scenario questions under time discipline; afterwards check your answer against the keys for omissions, log errors in an error book and tag each with its thread. Concept maps weave the threads: write a product at the centre and let cycle, materials, systems and intellectual property branch out. For example, centring on an automatic umbrella links open-versus-closed-loop judgement, aluminium selection, and patent and registered-design protection — one map spanning the syllabus.

5Worked example Example
Worked example: A start-up has designed a smart water bottle featuring a novel insulation structure, a distinctive form, a brand logo and a companion mobile app. Identify what each of the four kinds of intellectual property would protect here, and how the company should arrange them.
- The insulation structure is a technical solution — consider a patent to protect the working principle from imitation.
- The distinctive form is the product's appearance — register it as a design to stop others copying the shape.
- The brand logo can be registered as a trademark so consumers can identify the source and imitators are barred.
- The mobile app is an original work with automatic copyright, covering its interface graphics and text.
- Answer: A patent guards the structure, a registered design guards the form, a trademark guards the brand and copyright guards the app — four rights, different objects, forming one full protection. The answering key is to classify each result as technology, appearance, mark or original work, then match the right category, and to remind that registered rights should be filed early before others race ahead.
