Questions and Answers

According to Section 16(1) of the Patents Act, an invention meets the industrial application criterion only if it can be mass-produced in a factory setting, excluding fields such as handcrafted artisanal goods.

False (B)

A renowned cardiac surgeon develops a novel surgical procedure that significantly reduces recovery time for patients undergoing heart valve replacements. Considering Section 16(2) of the Patents Act, which statement accurately reflects the patentability of this procedure?

  • The surgical procedure is patentable, as it leads to tangible improvements in patient recovery and healthcare efficiency.
  • The surgical procedure is not patentable, as methods of treatment by surgery on the human body are excluded from being considered capable of industrial application. (correct)
  • The surgical procedure is patentable only if it incorporates a new medical device that is also patented.
  • The surgical procedure is patentable because it is a process used in the medical field and thus meets the criteria for industrial application.

A pharmaceutical company patents a new chemical compound demonstrating significant efficacy in treating a rare genetic disorder. The patent specification sufficiently details the compound's synthesis and its mechanism of action. However, its in vivo efficacy data included in the patent is deemed unreliable because the experiments were not repeated. According to Section 25(4) of the Patents Act, which of the following is most likely?

  • The patent is likely valid, as long as the specification allows someone skilled in the art to perform the invention, even if some experimental data is questionnable. (correct)
  • The accuracy of scientific data is irrelevant so long as the method is clearly and completely described.
  • The patent is automatically invalid because the _in vivo_ efficacy data is unreliable, regardless of other evidence of its efficacy.
  • The patent is provisionally valid until independent verification of the in vivo efficacy of the compound is presented.

Study Notes

Industrial Applicability

  • Patent protection applies to inventions, distinguishing them from mere discoveries.
  • An invention must be capable of industrial application
  • Section 16(1) of the Patents Act states that an invention is considered industrially applicable if it can be made or used in any industry, including agriculture.
  • Section 16(2) specifically excludes methods of treatment or diagnosis on the human or animal body from being considered industrially applicable, including surgery, therapy, and diagnosis.
  • Section 16(3) clarifies that even if a product is intended for use in excluded methods of treatment or diagnosis, it can still be considered industrially applicable

Industrial Applicability Scenario

  • A company develops a new surgical technique for repairing damaged ligaments. While the technique itself cannot be patented due to the exclusion of surgical methods, a specially designed surgical tool created specifically for this technique could potentially be patented because it is a product with industrial application beyond just the surgical procedure.

Sufficiency

  • Section 25(4) of the Patents Act requires that the patent application clearly and completely disclose the invention in a manner that allows a person skilled in the art to perform it.
  • The "patent bargain" entails specifying the invention in such a way that teaches an artist how to recreate it when the patent term expires, benefiting both the inventor during the term and the public afterward, as foundation of the modern patent law.
  • The test for sufficiency is a factual question based on the invention's nature and the case's circumstances.
  • The two-step test for sufficiency involves identifying the invention and what it enables a skilled person to do, then assessing whether the specification enables them to do it.

Sufficiency Scenario

  • An inventor claims a new type of battery with enhanced energy density. The inventor must provide enough details on the materials used and the manufacturing process so that a battery engineer could reproduce the enhanced energy density.

Offensive or Immoral Behaviour

  • Section 13(2) of the Patents Act states that an invention is not patentable if its publication or exploitation would encourage offensive, immoral, or anti-social behaviour.
  • Section 13(3) clarifies that behaviour is not deemed offensive, immoral, or anti-social solely because it is prohibited by Singapore law.

Offensive or Immoral Behaviour Scenario

  • Suppose an inventor creates a device which is designed to specifically disrupt banking systems across the globe, and it is argued that its publication would encourage unlawful activity. This invention might be considered unpatentable due to encouraging anti-social behavior.

Application and Grant Process

  • The patent application process typically takes 2 to 4 years, depending on the invention's complexity and the examination process

Filing Date

  • Section 26 of the Patents Act is a key component, as novelty and inventive step are assessed using the priority date, usually the filing date, guided by Section 17(1) along with Sections 14 and 15
  • The priority date may predate the filing date given a priority claim, excluding prior art as per Section 17

Publication

  • A patent application is typically published as soon as possible after 18 months from the filing or priority date, following Section 27 of the Patents Act and Patents Rule 29(1).
  • An applicant can request early publication according to Section 27(2) of the Patents Act to expedite the patent grant.
  • Publication can result in the loss of protection as confidential information while application forms become prior art, potentially worldwide
  • An applicant can seek damages for patent infringement backdating to publication per Section 76 of the Patents Act
  • Term of patent per Section 36(1) of the Patents Act, a granted patent is effective from the date of certificate issue until 20 years from filing.
  • Patents Rule 51(1) details that keeping a patent active requires annual renewal fees starting from the end of the 4th year after filing, within a period close to each filing anniversary.

Pre-Filing Considerations

  • Key considerations include disclosure of the invention, filing strategy, ownership, and IP due diligence.
  • It is important to keep an invention confidential before filing to avoid pre-filing disclosures impacting novelty and inventive step.
  • Legislative changes made in 2017 to Patents Act Section 14(4)(e) and Patents Rule 8 have expanded the grace period.
  • A filing strategy should align with business goals and budget, impacting filing location and method.

Employee Inventions

  • Section 49(1) determines that an invention made by an employee belongs to the employer if it was made in the course of their normal duties or specifically assigned duties, with reasonable expectation of invention
  • If, because of the employee's duties' nature and specific responsibilities, they had a special obligation to further the employer's interests, the invention also belongs to the employer
  • Section 50(1) states that provisions regarding employee inventions do not apply unless the employee was mainly employed in Singapore or their employment location couldn't be determined, but the employer had a Singapore business location
  • Section 50 (4) states that the Act does not prevent agreements or contracts about invention rights

Employee Inventions Scenario

  • Suppose an engineer is hired for research and development, and is assigned the specific task of improving battery longevity. Any invention or improvement in battery life resulting from their work is most likely the property of the company, due to the specific assignment.
  • Suppose any employment contract specifies the ownership of inventions

IP Due Diligence

  • Conducting due diligence before filing for a patent is useful to search patent and non-patent literature

Acts of Infringement

  • Infringing a product patent includes making, disposing of, offering to dispose of, using, importing, or keeping the patented product, whether for disposal or otherwise.
  • For a process patent, infringement includes using or offering the process for use and, concerning the product obtained from the process, disposing of, offering to dispose of, using, importing, or keeping it.

Claim Construction

  • Claim construction involves literal construction and purposive approach.

Literal Construction

  • Literal claim interpretation could be exploited by those seeking to bypass the patent monopoly by making minor variations

Purposive Approach

Purposive Approach

  • Purposive assessment is what a person skilled would understand for patentee to have used the language of the claim so that fair protection applies to third parties, who need to rely on patent claims.
  • The doctrine of equivalents covers substantially the same function, way, and results; rejected in Maka, but affirms the purposive test

Defences

  • As per Section 66(1), a defence exists if the alleged infringement occurred when the patent was not in force; a counterclaim can argue for patent revocation.
  • Section 66(2) defines defences such as acts done privately for noncommercial purposes or for experimentation

Defence Scenario

  • Defences to patent infringement: Evidence demonstrates that the alleged infringing act was done for non-commercial, private purposes, such as a hobbyist experimenting at home.

Restrictions on Relief

  • Section 69(1) limits remedies if the defendant was unaware of the patent's existence and had no reasonable basis to believe it existed.
  • The burden of proof lies with the defendant to demonstrate they were unaware of the patent.
  • Per Section 69(2), awareness can be shown if "patent" or "patented" accompanies the patent number. Example: "Singapore Patent No. xyzxyz".

Introduction to Revocation Proceedings

  • Revocation can occur if a patent is cited against an applicant's own patent application, in response to a lawsuit for patent infringement, or if a patent blocks freedom to operate.
  • Actions to to address these matters include applying to revoke a patent (examinable), applying for binding re-examination (non-examinable), or challenging validity by defence or counterclaim.

Revocation: Application vs Re-Examination

Feature Revoke a Patent Re-examine a Patent (non-examinable)
Basis Section 80, Rules 80-84 Section 38A, Rule 52A
Filing High Court or Registrar Registrar
Parties Inter partes (both parties involved) Ex parte (one-sided)
Process Both parties submit evidence, Court/Registrar decides Applicant has no further role, between Registrar and patentee
Outcome Longer, more expensive Shorter, less expensive but applicant cannot comment

Grounds of Revocation

  • According to Section 80(1), grounds for revocation include the invention not being patentable (e.g., not novel or inventive) or the patent being granted to an unentitled person.

Process of Revocation

  • Procedure per Section 82(1)(d) and Rule 80: application, counter-statement, specification amendment, applicant evidence, proprietor evidence, and applicant reply.

Effect and Consequences of Revocation

  • As per Section 80(5)(a), the revocation of a patent has serious consequences
  • Per Section 80(5)(b), if it's partially invalid, the patentee can amend specification with approval
  • By Section 80(7), revocation begins on grant day

Scenario

  • A competitor successfully proves that a patented technology was already publicly disclosed before the patent application. If the effect of revocation means the original patent grant is voided; serious consequences for the patentee
