Bonutti (primarily through Bonutti Research, Bonutti Skeletal Innovations, and related entities like P Tech LLC) has licensed an extensive portfolio of over 450 issued patents to major medical device companies.

Dr. Peter Bonutti’s inventions are foundational to modern minimally invasive surgery (MIS), robotic-assisted surgery, and joint arthroplasty.

The following breakdown details the key patents and technologies Bonutti has licensed, categorized by the licensee.

‍

1. Zimmer Biomet - Zimmer Biomet is one of Bonutti's most significant licensees. The agreements cover core technologies for knee replacements and robotics.

‍Licensed Technology:

• Personalized Knee Systems: Patents supporting the Persona® and NexGen® knee systems.
• Robotic Surgery: Patents supporting the ROSA® robotic knee system, specifically covering robotic unicompartmental and total knee arthroplasty.

‍Key Patents:

2. Stryker - Stryker has licensed Bonutti’s technology to support its leadership in minimally invasive joint replacement.

• US 9,301,845: Related to instrumentation for knee arthroplasty (used in Persona/NexGen).
• US 9,629,687 & US9,585,725: Cover robotic systems and computer navigation for joint replacement.

‍Licensed Technology:

• Minimally Invasive Knee Arthroplasty: Stryker’s annual reports have credited Bonutti’s innovations with enabling their minimally invasive surgical techniques.
• Suture Anchors: Bonutti founded Multitak, a company focused on soft tissue fixation (suture anchors). While Multitak was a Bonutti start-up, the underlying"all-suture" or "soft" anchor technology concepts are widely licensed or cited in the industry, including by players like Stryker and Arthrex.

3. Medtronic (via Kyphon & Covidien) - Bonutti has multiple streams of technology licensed to companies now owned by Medtronic.

• Kyphon (Spine): In 2002, Kyphon(acquired by Medtronic) licensed a portfolio of Bonutti patents related to vertebroplasty and kyphoplasty. This technology allows for the minimally invasive treatment of spinal compression fractures using expandable balloons.
• Covidien (Surgical Stapling): Bonutti is listed as a licensor to Covidien (now Medtronic) for surgical stapling technologies. This likely relates to Tri-Staple™ or similar endoscopic stapling technologies that use variable-height staples to reduce tissue trauma

4. Biomet (Legacy) - Before merging with Zimmer, Biomet entered a specific licensing agreement in 2006.

‍Licensed Technology:

• MarcTec LLC Portfolio: Biomet licensed patents from MarcTec (a Bonutti entity) related to suture anchors and minimally invasive soft tissue repair.
• Litigation Settlement: This license resolved disputes over patents such as US 5,921,986 ("Bonesuture") and US 6,638,279 ("Method of positioning body tissue").

5. Smith & Nephew - Smith & Nephew is another major licensee, though the relationship has involved significant litigation (Inter Partes Reviews) to define the scope of the patents.

‍Licensed Technology:

• Knee Arthroplasty Instrumentation: The licenses cover instruments and methods for minimally invasive knee surgery,specifically regarding how guides and cutting blocks are positioned with out large incisions.

6. Emerging & Other Technologies - Bonutti Research is actively developing and licensing technologies in new fields beyond standard orthopedics.

• Biodegradable Implants (Magnesium): Bonutti has a growing portfolio of "green" medical technologies,specifically biodegradable magnesium alloys that provide structural support (like screws or plates) but dissolve safely in the body overtime, eliminating the need for removal surgery.
• Joint Active Systems (JAS): This is a Bonutti-founded company (rather than a pure licensee) that manufactures range-of-motion therapy devices using his Static Progressive Stretch(SPS) technology.
• Unity Ultrasonic: Another Bonutti venture focused on ultrasonic technology for surgical tissue removal and welding, which has potential applications in future licensing deals.

Summary of Key Patent Families

• If you are looking at specific patent documents, Bonutti’s portfolio is often assigned to entities including Bonutti Skeletal Innovations LLC, P Tech LLC, and MarcTec LLC. The patents generally cluster around these themes:
  • Minimally Invasive Access: Retractors and methods to operate through smaller incisions.
  •  Tri-Staple / Variable Compression: Stapling tissue with varying degrees of tightness to prevent necrosis.
  • Expandable Implants: Cages and shims that expand inside the body (spine/knee).
  • Robotic Navigation: Systems that track bone position during surgery.

In addition to the primary agreements with Zimmer Biomet and Stryker, Bonutti has licensed technology through several specific corporate entities, most notably Bonutti Skeletal Innovations LLC and PTech LLC.

‍

These agreements often result from patent enforcement campaigns (litigation) that end in settlements and licensing deals.

‍

1. Bonutti Skeletal Innovations LLC (Spine & Knee Focus) - This entity holds the bulk of the orthopedic and spine patents and has been the primary vehicle for licensing deals following litigation.

• Globus Medical (Spine):
  • Status: Confirmed Licensee.
  •  Details: Following a patent infringement lawsuit filed in 2014 regarding spinal spacers and wedge implants,the parties reached a settlement. Bonutti Skeletal Innovations granted Globus Medical a non-exclusive license to 14 U.S. patents and 2patent applications.
  • Technology: The licensed patents relate to methods for changing the spatial relationship between bones (e.g.,expanding the disc space during spinal fusion).
• ConforMIS (Customized Knee Implants):
  • Status: Settlement / Likely License.
  • Details: Bonutti sued ConforMIS in2012 alleging infringement of patents related to minimally invasive knee arthroplasty (e.g., US Patent 7,806,896). The case was resolved via settlement,which typically involves a confidential licensing component or cross-licensing arrangement.
  • Technology: Methods for knee arthroplasty that minimize tissue damage, which overlapped with ConforMIS's patient-specific instrumentation techniques.
• Smith & Nephew:
  • ‍Status: Settlement / License.
  • ‍Details: Bonutti asserted multiple patents against Smith & Nephew regarding knee instrumentation. The litigation ended with a dismissal "without prejudice" in 2014, and Dr. Bonutti’s professional bio lists Smith & Nephew as a licensee, confirming the dispute was resolved through a licensing deal.

•  Synthes (DePuy Synthes / J&J):
  • ‍Status: Bio-Listed Licensee.
  • ‍Details: While DePuy Synthes has challenged Bonutti patents in Inter Partes Reviews (IPRs), Dr. Bonutti’s corporate profile explicitly lists Synthes as a company that has leveraged histechnology. This likely covers trauma and fixation devices.

2. PTech LLC (Ultrasonic & Advanced Materials) - P Tech LLC is a less visible but highly critical Bonutti entity. It holds patents related to ultrasonic energy, tissue welding, and biodegradable fasteners.

• Unity Ultrasonic:
  • ‍Status: Internal Venture /Technology Platform.
  • ‍Technology: P Tech holds the IP for the Unity Ultrasonic system. Instead of just licensing this out, Bonutti developed it into a standalone 510(k) cleared product.
  • ‍Licensees: The foundational"ultrasonic welding" and "biodegradable fastener"technology held by P Tech has been licensed to major players like Covidien(now Medtronic) and Stryker for use in their own anchor and tissue-welding systems.

3. MarcTec LLC (The"Failed" Licensing Attempt) - It is important to note that not all Bonutti entities successfully license their portfolios.

• Cordis (Johnson & Johnson): Bonutti’s entity MarcTec LLC sued Cordis over drug-eluting stent technology.
• Outcome: No License. The court found that MarcTec had misrepresented the patent claims and ruled in favor of Cordis (J&J), ordering MarcTec to pay attorney fees. This serves as a rare example where a Bonutti enforcement campaign did not result in a license.

4. Other Licensees (Listed in Corporate Bios) - Dr. Bonutti’s official professional summaries list several other major corporations as licensees. While the specific press releases for these deals are often confidential, the relationships are publicly claimed:

• Hitachi: Likely related to imaging or navigation technologies integrated with surgical tools.
• ArthroCare (acquired by Smith & Nephew): Likely related to soft tissue fixation or wand-based ablation technologies.
• US Surgical (acquired by Covidien/Medtronic): Related to early laparoscopic and stapling innovations.
