Patent Application (Hong Kong)

A Patent Application in Hong Kong sets out the particulars an applicant must provide to obtain the approval concerned.

The Patents Ordinance (Cap. 514), enacted in 1997 and amended by the Patents (Amendment) Ordinance 2016, governs all aspects of patent protection in Hong Kong. Section 9 of Cap. 514 defines the patentability requirements: the invention must be new (not previously disclosed anywhere in the world before the priority date), involve an inventive step (not obvious to a person skilled in the relevant field), and be capable of industrial application. Section 9 also lists excluded subject matter including discoveries, scientific theories, aesthetic creations, mental acts, business methods, and methods of treatment of the human body.

The Intellectual Property Department, headquartered at Wu Chung House in Wan Chai, administers patent applications in Hong Kong and maintains the Hong Kong Patents Register. The IPD is also responsible for the Trade Marks Registry under the Trade Marks Ordinance (Cap. 559), the Designs Registry under the Registered Designs Ordinance (Cap. 522), and the Copyright Registry under the Copyright Ordinance (Cap. 528). Patent applicants in Hong Kong may also interact with the World Intellectual Property Organization (WIPO) through the Patent Cooperation Treaty (PCT), under which a single international application may enter the Hong Kong national phase via the IPD.

Hong Kong's status as a major financial centre and innovation hub — with a significant cluster of technology companies, fintech firms, and biomedical research institutions in areas such as Kowloon East, Pak Shek Kok Science Park, and Hong Kong Science and Technology Parks Corporation (HKSTP) facilities in Sha Tin — makes patent protection strategically important for businesses operating in or exporting to the Greater Bay Area, which encompasses Shenzhen, Guangzhou, and eight other Guangdong cities. A Hong Kong standard patent based on a CNIPA grant provides protection in Hong Kong SAR, while a separate China patent covers the mainland — the two jurisdictions maintain independent intellectual property systems.

The Courts of Hong Kong — specifically the Court of First Instance and the Court of Appeal — have jurisdiction over patent infringement and validity disputes. Patent litigation in Hong Kong is conducted under the Rules of the High Court (Cap. 4A), and the Court may appoint scientific advisers to assist in technically complex cases. The Hong Kong Intellectual Property Exchange (HKIPX) also provides a platform for licensing and commercialisation of patents in Asia.

The Intellectual Property Department in Hong Kong processes standard patent applications under the Patents Ordinance (Cap. 514) with reference to the examination conducted by a designated patent office — the China National Intellectual Property Administration (CNIPA), the European Patent Office (EPO), or the United Kingdom Intellectual Property Office (UKIPO). Section 9 of Cap. 514 defines a patentable invention as one that is new, involves an inventive step, and is capable of industrial application. Novelty is assessed globally — a prior publication, use, or disclosure anywhere in the world before the Hong Kong priority date will defeat novelty under Section 9(1) of Cap. 514. The preparation of a patent specification with accurate claims, a detailed description, and supporting drawings is a technical exercise that determines the scope of protection the patent will afford, and errors in claim drafting cannot generally be corrected after the patent is granted.

Short-term patents under Section 113 of Cap. 514 provide an alternative for inventions with a commercial lifespan of less than eight years — particularly products with rapid development cycles such as consumer electronics, mobile applications, and medical devices. A short-term patent requires a registered patent agent or a person qualified to act under Section 149 of Cap. 514 to conduct a prior art search, but does not require full substantive examination. The trade-off is that a short-term patent is more vulnerable to invalidity challenges than a standard patent that has passed full examination.

A Patent Application in Hong Kong is needed when an inventor, company, or research institution wishes to obtain exclusive rights to a new invention before it is disclosed, commercialised, manufactured, or exported. Filing a patent application at the Intellectual Property Department (IPD) establishes a priority date — the effective date from which novelty and inventive step are assessed under the Patents Ordinance (Cap. 514). Any public disclosure of the invention before the priority date — through a published paper, conference presentation, product launch, or social media post — destroys novelty and prevents a valid patent from being granted.

A Patent Application is needed before entering the market. Companies planning to manufacture patented technology in Hong Kong, license it to manufacturers in mainland China or Southeast Asia, or sell patented products through Hong Kong's trading networks should secure patent protection before any commercial activity begins. Hong Kong Science and Technology Parks Corporation (HKSTP) tenants — including biomedical, electronics, and data technology companies — are typically advised to file patent applications as a condition of technology transfer agreements and investment rounds.

Startups raising venture capital or seeking investment from Hong Kong Growth Enterprise Market (GEM) or Main Board listed corporate investors often need to demonstrate a patent portfolio or pending patent applications as evidence of defensible intellectual property. Investment agreements for Series A and later rounds frequently include representations about patent ownership and freedom to operate, making prior filing with the IPD a commercial necessity.

Research institutions in Hong Kong — including the University of Hong Kong, Hong Kong University of Science and Technology, the Chinese University of Hong Kong, and City University of Hong Kong — file patent applications through their technology transfer offices when researchers develop commercially applicable inventions. The Research Grants Council and the Innovation and Technology Fund administered by the Innovation and Technology Commission support patent filing by Hong Kong researchers through grant programmes.

A short-term patent application at the IPD is appropriate for inventions with a shorter commercial lifecycle — consumer electronics, fashion technology, certain software-implemented inventions — where the 8-year protection term is sufficient. A standard patent re-registration is appropriate for inventions with a longer commercial lifecycle such as pharmaceutical compounds, medical devices, and industrial processes where 20-year protection is commercially significant.

A Patent Application in Hong Kong prepared through forms-legal.com covers the essential components for either a short-term patent application or a standard patent re-registration at the Intellectual Property Department (IPD) under the Patents Ordinance (Cap. 514).

Applicant and Inventor Details: The application identifies the full legal name and address of the applicant — which may be an individual, a Hong Kong company registered with the Companies Registry under the Companies Ordinance (Cap. 622), or a foreign entity — and the names and addresses of all inventors. Where the applicant is not the inventor, an assignment or deed of assignment from the inventor to the applicant must be in place, as only the true inventor or their assignee may apply for a patent under Section 50 of Cap. 514.

Title and Description of the Invention: The application includes a concise and accurate title, followed by a detailed technical description — the specification — that fully discloses the invention in sufficient detail to allow a person skilled in the relevant field to reproduce it. The description must support all the claims and must not conceal material information about how the invention works.

Claims: The claims define the legal scope of the patent protection sought. Each claim must be clear, concise, and fully supported by the description. Independent claims define the broadest protection; dependent claims add specific limitations. The scope of claims is critical — overly broad claims may be invalidated for lack of novelty or inventive step, while overly narrow claims leave competitors free to design around the patent.

Drawings: Technical drawings are required where necessary to understand the invention. Drawings must comply with the IPD's prescribed format requirements regarding line weight, scale, and reference numerals.

Abstract: A concise summary of the technical disclosure — typically 150 to 250 words — is required for publication purposes. The abstract must not be used to define the scope of the patent.

Priority Claim: Where the application claims priority from a prior overseas filing under Section 16 of Cap. 514 and the Paris Convention, the priority country, application number, and filing date must be stated, and a certified copy of the prior application must be submitted within the prescribed period.

Filing Fees: The prescribed filing fee under the Patents (Fees) Rules is paid at submission. For a short-term patent, a search report request fee is also payable. Renewal fees are payable annually to maintain the patent in force.

Search Report (Short-Term Patent): A short-term patent application requires a search report from a designated search authority — such as the European Patent Office, the UKIPO, or CNIPA — to identify prior art relevant to the claims. The IPD may not grant a short-term patent without a filed search report.

Designated Patent Documents (Standard Patent): For a standard patent re-registration, the application must identify the granted patent from the designated office (CNIPA, EPO, or UKIPO), the grant date, and the grant number. The IPD verifies this information against the designated office's records before registering the standard patent in Hong Kong. The forms-legal.com Patent Application template for Hong Kong is structured for both short-term and standard patent applications and includes all required fields.

Prior Art Search Results: For short-term patent applications under Section 113 of Cap. 514, a prior art search conducted by a registered patent agent is submitted with the application. The search covers published patents, patent applications, and non-patent literature — including academic journals, technical standards, and commercial product descriptions — to assess whether the invention meets the novelty and inventive step requirements of Section 9 of Cap. 514. A thorough prior art search conducted before filing reduces the risk of investing in a patent application that will be invalidated after grant. The forms-legal.com Patent Application support package includes guidance on commissioning prior art searches from patent agents registered with the Intellectual Property Department.

National Phase Entry and PCT Applications: Where the inventor has filed an international patent application under the Patent Cooperation Treaty (PCT) administered by the World Intellectual Property Organization (WIPO), the Hong Kong national phase entry under Cap. 514 must be filed within 31 months of the PCT international filing date or the priority date, whichever is earlier. Section 121 of Cap. 514 governs the requirements for entering the national phase in Hong Kong from a PCT application, including translation requirements where the PCT application was not filed in English or Chinese. The forms-legal.com Patent Application guide addresses PCT national phase entry timelines for inventors who have filed internationally through the PCT route.

A Patent Application in Hong Kong is filed with the Patents Registry of the Intellectual Property Department (IPD) under the Patents Ordinance (Cap. 514). Follow these steps depending on whether you are pursuing a short-term patent or a standard patent re-registration.

1. Determine the correct route. A short-term patent under Part XIV of Cap. 514 is filed directly with the IPD and grants up to eight years of protection. A standard patent currently requires a prior granted patent from the China National Intellectual Property Administration, the European Patent Office designating the United Kingdom, or the UK Intellectual Property Office — then a re-registration application at the IPD within six months of that grant date.

2. Confirm inventorship and ownership. Under Section 50 of Cap. 514, only the true inventor or their assignee may apply. Where the applicant is not the inventor — for example, an employer claiming rights to an employee's invention — a deed of assignment from the inventor to the applicant must be executed before filing.

3. Complete the prescribed request form. Obtain the current form from the IPD at 24/F, Wu Chung House, 213 Queen's Road East, Wan Chai. Enter the applicant's full legal name and address, all inventors' names and addresses, the title of the invention, and the type of application. For a priority claim under Section 16 of Cap. 514, state the prior application's country, application number, and filing date.

4. Prepare the specification. The specification must include a detailed description that enables a person skilled in the relevant technical field to reproduce the invention, one or more claims defining the scope of protection, any drawings necessary to understand the invention in IPD-prescribed format, and an abstract of 150 to 250 words. Claims must be fully supported by the description — unsupported claims render the patent vulnerable to invalidation.

5. Commission a prior art search (short-term patent). For a short-term patent application, a search report from a designated search authority — such as the European Patent Office, the UK Intellectual Property Office, or the China National Intellectual Property Administration — must be requested. The search identifies prior art relevant to the claims and must be filed with or after the application within the IPD's prescribed period.

6. Attach the priority document if claiming priority. A certified copy of the prior application from the Convention country must be submitted within the period specified by the IPD. Priority must be claimed within 12 months of the earliest prior filing date under Section 16 of Cap. 514.

7. Pay the prescribed fees. Filing fees are set under the Patents (Fees) Rules made under Cap. 514 and are published on the IPD's official fee schedule — verify the current amounts before submitting, as fees are periodically revised. For a short-term patent, the filing fee and the search report request fee are payable at lodgment. Annual renewal fees for a granted patent are payable from the third year to maintain the patent in force; failure to pay renewal fees causes the patent to lapse.

8. File with the Intellectual Property Department. Submit the completed request form, specification, drawings, abstract, priority document (if applicable), and fee payment to the Patents Registry of the Intellectual Property Department at 24/F, Wu Chung House, 213 Queen's Road East, Wan Chai, Hong Kong — in person, by post, or through the IPD's electronic filing system where available. Retain the IPD's receipt confirming the filing date, as this date establishes the priority date for novelty assessment.

9. Respond to office actions. The IPD will conduct a formalities examination. Respond promptly to any objection or requirement within the prescribed period to avoid the application being treated as withdrawn.

10. Retention. Keep all application documents, the IPD filing receipt, correspondence with the IPD, and renewal payment records for the full life of the patent.
