Enhancing the Patentability of Algorithms

As the pace of Digital Transformation accelerates, algorithms are playing a crucial role in diverse fields such as Artificial Intelligence (AI), Big Data, Machine Learning (ML), and FinTech. Consequently, inventors and companies are actively considering patent applications to effectively protect their innovative algorithms. However, with patent examination trends in the software and IT sectors becoming increasingly stringent, merely filing an application does not guarantee a high likelihood of registration. This column examines key strategies and important points for maximizing the patentability of algorithms.

1. Clearly Present the 'Technical Problem' Solved and the 'Technical Effect' Achieved by the Algorithm

For an algorithm patent to transcend being a mere idea and secure patentability, it is essential to specifically articulate the technical problem the algorithm aims to solve and the technical effects obtained thereby.

• Technical Problem:
  • Clearly describe how the algorithm improves upon or resolves limitations present in existing systems or processes.
  • Emphasize its implementability in real industrial settings, going beyond mathematical formulas or simple concepts.
• Technical Effect:
  • Present performance improvements in areas like big data analysis, image processing, or resource optimization using specific figures or examples.
  • Highlight concrete technical advantages such as computational efficiency, reduced network resource usage, or faster data processing speeds.

These technical problems and effects are core elements satisfying the 'industrial applicability' requirement under patent law. Detailing them in the patent specification significantly enhances the likelihood of registration.

2. Emphasize Linkage to Hardware and Specific Systems

There is a perception that purely software-based ideas face challenges in patent registration. Indeed, domestic and international patent examination practices tend to favor inventions where software is combined with hardware and implemented on a specific system.

• Specify System Architecture:
  • Provide examples of specific hardware components like servers, sensors, networks, or cloud environments, and illustrate how the algorithm operates within this context.
  • Describe advantages in hardware operation, or improvements in efficiency or stability resulting from the algorithm's application.
• Highlight Hardware Dependency:
  • Demonstrate that substantial technical synergy occurs when integrated with specific elements like a particular CPU architecture, GPU parallel processing, or IoT device sensors.
  • This underscores its significance as a 'technical means' rather than just an abstract idea.

By describing hardware and system requirements together, you can clearly show that the invention contributes to solving a technical problem.

3. Describe Implementation Examples and Data Flow Concretely

Presenting only abstract formulas or algorithm structures in the specification can make it difficult to sufficiently convey the invention's feasibility and superiority. Therefore, it is crucial to include concrete implementation examples (embodiments) and data processing flows (flowcharts).

• Embodiments (Examples):
  • Detail one or more scenarios showing the flow of input data (e.g., images, voice, text, financial transaction information), the processing method, and the output (e.g., analysis results, predicted values).
  • Include potential issues during implementation and their solutions to demonstrate practicality and effectiveness.
• Data Flow Diagrams (Flowcharts):
  • Provide a visual representation of step-by-step computational processes, state transitions, and output values to enhance understanding.
  • Explicitly describe the technical features at each step to highlight the algorithm's original ideas and effects.

Drafting the specification with such concrete examples makes it easier for examiners to grasp the invention's utility and originality, thereby increasing the chances of patent registration.

4. Actively Emphasize 'Superiority' and 'Differentiation' Compared to Prior Art

To be registered, a patent must possess features that are new (novelty) compared to prior art and demonstrate an inventive step beyond existing technology. Therefore, it is essential to conduct a thorough prior art search, analyze the differences between the invention and existing technologies, and emphasize the resulting superiority.

• Prior Art Analysis:
  • Identify the algorithm structures and data processing methods used by competitors or in existing inventions beforehand.
  • Compare with similar registered algorithm patents to pinpoint key differentiating factors.
• Quantitative Proof of Effects:
  • Present the invention's effects using objective metrics like processing speed improvements, cost reductions, or error rate decreases.
  • Use benchmark test results or experimental data presented graphically for quantitative appeal.

Clearly demonstrating the invention's actual contribution to technological advancement helps examiners readily recognize the inventive step.

5. Prepare an International Filing Strategy Concurrently

Algorithm patents, being based on digital technology, have a high potential for commercialization across borders. Therefore, alongside domestic filing, a strategy for PCT international applications or direct foreign filings should be established.

• US Patent Applications:
  • While examination of software patents has intensified post-Alice, registration is still possible if the solution to a technical problem is described concretely.
  • Emphasis should be placed on hardware integration, specific implementation methods, and clear technical effects during drafting.
• Europe (EPO), China, Japan, etc.:
  • Examination standards for software-related inventions differ somewhat by country, requiring familiarity with each jurisdiction's practices.
  • For example, consider the EPO's strict focus on 'technical contribution.'
  • China and Japan have similarities to Korea, but detailed step-by-step implementation descriptions and articulation of technical effects are crucial.

To systematically protect algorithm patents in the global market, an application strategy reflecting the patent laws and examination trends of various countries must be prepared from the early stages of invention.
