I. Introduction

This is the second article of the multi-part series discussing benefits of prosecuting patents under Patent Prosecution Highway or PPH. The first article can be accessed here. To recap, PPH is a set of initiatives promulgated by participating patent offices around the world to accelerate patent prosecution in countries of the participating patent offices. PPH allows participating patent offices to share information and to benefit from work performed by other participating patent offices, thereby reducing examination workload and improving quality of patents. Interested readers are invited to read the first article through the link provided.Continue Reading Benefits and Considerations for Patent Prosecution Under Patent Prosecution Highway in Australia, Canada, South Korea, and Japan

I. Introduction

Patent Prosecution Highway or PPH is a set of initiatives promulgated by participating patent offices around the world to accelerate patent prosecution in countries of the participating patent offices. PPH allows the participating patent offices to share information and to benefit from work performed by other participating patent offices, and thereby reducing examination workload and improving quality of patents.

Under PPH, prosecution of a patent application previously filed with a participating patent office can be fast-tracked in another participating patent office if the patent application meets certain requirements. This article provides a brief overview of benefits of filing patent applications under PPH and requirements by which the patent applications must satisfy in order to participate in PPH.Continue Reading Benefits and Considerations for Patent Prosecution under Patent Prosecution Highway in the U.S., Europe, China, and Singapore

In recent years, AI patent activity has exponentially increased. The figure below shows the volume of public AI patent applications categorized by AI component in the U.S. from 1990-2018. The eight AI components in FIG. 1 are defined in an article published in 2020 by the USPTO. Most of the AI components have experienced explosive growth in the past decade, especially in the areas of planning/control and knowledge processing (e.g., using big data in automated systems).

The Situation

Smart contracts are often mentioned in blockchain-themed patent applications and recited in claims. However, Examiners without a thorough understanding of this concept or unfamiliar with blockchain technology often equate smart contracts with legal or commercial contracts stored on blockchains. As a result, the Examiners may find claims directed to merely applying the blockchain technology to execute legal or commercial contracts, for example, as part of a commerce system, like hedging. See, e.g., Alice Corp. Pty. Ltd. v. CLS Bank Int’l, 134 S.Ct. at 2356 (citing Bilski v. Kappas, 561, U.S. 593, 611 (2010)).Continue Reading Distinguish “Smart Contract” From Abstract Idea To Pass Blockchain Patentability Scrutiny

Blockchain patent applications may be divided into two types: underlying technologies of blockchain, such as consensus methods, security, etc., and applications of blockchain in, e.g., fintech, legal, and other industries. In patent examination, the first type, because it recites underlying technology improvement, rarely elicits subject matter rejections. The second type, applications of blockchain, are often found to be directed to an abstract idea. This article analyzes a recent Patent Trial and Appeal Board (PTAB) decision in a blockchain patent application and explores drafting and prosecution strategies to anticipate subject matter scrutiny.
