II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,550,052 - “CONSOLE SYSTEM FOR THE TREATMENT OF SKIN”
- Issued: January 24, 2017.
The Invention Explained
- Problem Addressed: The patent background describes traditional dermabrasion and microdermabrasion techniques as painful, messy procedures that require significant healing time and can cause undesirable side effects like bleeding or raw-looking skin (’287 Patent, col. 1:44-54).
- The Patented Solution: The invention is a skin treatment system featuring a console that manages fluid flow from multiple treatment material containers through a manifold to a handpiece. The system is designed to allow a user to select different treatment liquids and simultaneously use a vacuum source to draw waste material and abraded skin away from the treatment tip through a separate conduit, creating a more controlled and less messy procedure (’052 Patent, Abstract; col. 5:15-34).
- Technical Importance: This integrated approach sought to combine the benefits of exfoliation, targeted serum delivery, and waste extraction into a single, user-controlled console system, improving upon prior art methods that often treated these as separate, less-controlled steps (’052 Patent, col. 5:15-24).
Key Claims at a Glance
- The complaint asserts at least independent Claim 1 (Compl. ¶40).
- Claim 1 requires:- A system for performing a skin treatment procedure
- A console including a manifold, in fluid communication with a first and at least a second fluid container
- The containers are configured to hold a liquid treatment material

Identified Points of Contention
- Scope Questions: The complaint alleges the MIRApeel system contains an "internal manifold" (Compl. ¶40, p. 13). A potential point of dispute may be whether the accused product's internal fluid-routing components meet the structural or functional definition of a "manifold" or "manifold system" as understood in the patents.
- Technical Questions: A central technical question arises from the functional claims related to the vacuum source. Both the ’052 and ’477 Patents claim a vacuum that does more than just remove waste; it is also claimed to "draw" or "help transfer" treatment material to the handpiece. The complaint supports this with marketing materials describing a "closed-loop technology" (Compl. Ex. 11). The case may turn on evidence demonstrating whether the accused device's vacuum system is technically configured to perform this delivery-assistance function, or if its primary and intended function is limited to waste removal.
V. Key Claim Terms for Construction
Term: "manifold" / "manifold system"
- Applicable Patents: ’052 and ’477 Patents
- Context and Importance: This term is foundational to the architecture of the claimed inventions. The complaint alleges the accused MIRApeel device contains an "internal" manifold. The construction of this term will be critical to determining if the accused product's internal fluid channeling architecture falls within the scope of the claims.
- Intrinsic Evidence for Interpretation:- Evidence for a Broader Interpretation: The specifications use the term functionally, stating "A manifold system 24 can control the flow of treatment material from containers 26" (’052 Patent, col. 5:17-19). This functional language may support a construction that is not limited to a specific structure.
- Evidence for a Narrower Interpretation: The figures in the patents consistently depict the manifold (24) as a distinct, block-like component to which containers are attached (e.g., ’052 Patent, Fig. 1, 15A). A party could argue that the term should be construed as being limited to the structure disclosed in these preferred embodiments.
 
Term: "drawing treatment material...to the tip" / "help transfer...treatment material from the manifold system to the handpiece assembly"
- Applicable Patents: ’052 Patent / ’477 Patent
- Context and Importance: Practitioners may focus on this term because this functional language ascribes a dual purpose to the vacuum source: not only removing waste but actively assisting in the delivery of treatment fluid. The infringement allegation hinges on whether the accused device's vacuum is "configured to" perform this delivery function.
- Intrinsic Evidence for Interpretation:- Evidence for a Broader Interpretation: A party might argue that in any closed-loop system, a vacuum applied at the waste end will create a pressure differential that inherently "helps transfer" fluid throughout the system, thereby meeting the claim language's plain meaning. The patents describe an integrated system where suction and delivery are linked (’477 Patent, col. 5:11-24).
- Evidence for a Narrower Interpretation: The specifications primarily describe the vacuum's role in the context of removing waste and impurities from the skin (’477 Patent, col. 7:60-8:2). A party may argue that the term requires the vacuum to be specifically designed or configured for the purpose of assisting fluid delivery, rather than this being an incidental or inherent effect of a vacuum designed for waste removal.
 
VI. Other Allegations
Indirect Infringement
- The complaint alleges active inducement, asserting Defendants market and sell the MIRApeel system with knowledge and intent that customers will use it in an infringing manner. This is allegedly supported by providing instructions, training videos, and user manuals that encourage such use (Compl. ¶¶41, 52, 63, 74). Contributory infringement is also alleged on the basis that the MIRApeel system constitutes a material part of the patented invention, is not a staple article of commerce, and is especially made for use in an infringing manner (Compl. ¶¶43, 54, 65, 76).
Willful Infringement
- Willfulness is alleged based on both pre- and post-suit knowledge. The complaint alleges Defendants knew or should have known of the patents due to their status as competitors, Plaintiff's patent marking on its website since at least June 2018, and actual notice letters sent on August 6 and August 22, 2024 (Compl. ¶¶30-34, 37).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the term "manifold," which is depicted in the patents as a distinct component, be construed broadly enough to read on the alleged "internal" fluidics system of the accused MIRApeel device?
- A key evidentiary question will be one of functional operation: does the accused product's vacuum system merely remove waste from the skin, or is it technically configured to perform the specific, claimed dual function of also actively "drawing" or "transferring" treatment fluid from the console to the handpiece tip? The outcome may depend on evidence regarding the intended design and actual operation of the MIRApeel's fluid dynamics.
