• Johnson & Johnson is the leading applicant in surgical robotics based on the size and quality of its patent portfolio. Additionally, it has a commendable market quality that suggests extensive global market coverage (active patent families).
• Philips and Medtronic Inc. have comparable portfolio value indices. However, Philips’ market quality is marginally superior, suggesting its surgical robotics products have broader global coverage.
• Intuitive Surgical and Stryker Corp, present in the upper right quadrant, are also established players in surgical robotics. Their patent portfolios exhibit strong 360-quality, reflecting a robust statistical quality of the patents.
• Smith & Nephew, may have a smaller patent portfolio, but its 360-quality scores are high and therefore is backed by sound innovations that have a larger exploitation potential.
• Becton Dickinson Co, appears to have superior global market coverage, indicating a higher market quality compared to other companies, even though it holds fewer patent documents.
• Olympus Corp has been consistently improving its overall patent position in this space. While other companies might have overtaken it in surgical robot related patent filings, Olympus maintains a substantial portfolio size and with an overall portfolio quality of 45%, it positions itself as a potential contender in the field.

In conclusion, leading assignees such as Johnson & Johnson, Intuitive Surgical, Medtronic and Stryker Corp are prominent figures in the surgical robotics sector. Though not included in our analysis presented here, we came across multiple companies with smaller but exceptionally high-quality patent portfolios (reflected by a strong 360-quality score). These can represent promising investment or acquisition opportunities for the larger players.
