ClearCorrect Eliminates Three Align Technology Lawsuits

USPTO Rejects Patent Claims of Fourth and Final Lawsuit
ROUND ROCK, TX-- November 12, 2015 - ClearCorrect, LLC, a leading U.S. manufacturer of clear aligners, has been successful once again in litigation brought against the Company by Align Technology, Inc. The United States Court of Appeals for the Federal Circuit cleared the Company of any liability in the International Trade Commission (ITC) investigation relating to certain Align patents, ending the ITC action initiated by Align in 2012. This resolves the third unwarranted and unsuccessful lawsuit Align has brought against ClearCorrect since 2011.
The November 10th Appeals Court decision is the latest in a series of favorable decisions for ClearCorrect in both the ITC and the United States Patent and Trademark Office (USPTO). “This decision solidifies the fact that the ITC is without jurisdiction to regulate electronic transmissions of data and all of the ITC’s rulings in the case are therefore null and void” said Michael D. Myers, ClearCorrect’s attorney in the case and a partner with the Houston, Texas law firm McClanahan Myers Espey, LLP.
"While the ITC has no authority or jurisdiction to judge the validity of these patents, the USPTO certainly does, and it has found substantial questions exist in all of the Align patents that it has reviewed thus far despite Align’s oral arguments and written responses to the contrary. The input of this expert agency reinforces the strength of ClearCorrect’s insistence that we do not infringe any valid patent rights. explains Scott A. McKeown, a partner with the Washington, DC law firm Oblon, McClelland, Maier & Neustadt who is leading ClearCorrect’s efforts at the USPTO.
Align’s final case against ClearCorrect is a patent infringement case in a Texas federal court that has been dormant since 2012 pending the resolution of the ITC actions. That remaining case, however, faces substantial hurdles in light of the ongoing cancellation proceedings of the USPTO, which have significantly progressed:
  •   6 of 9 patents asserted in the Texas suit are currently subject to USPTO cancellation
  •   The USPTO has agreed with ClearCorrect’s invalidity positions on over 75 claims across the first 6 patents
  •   The final 3 patents which ClearCorrect will be pursuing are largely overlapping in subject matter with the current
    Align originally filed two lawsuits against the company in 2011, followed a year later by two ITC actions. One of the 2011 lawsuits was settled last month when Align voluntarily dropped its claims in exchange for ClearCorrect’s dismissal of its counterclaims. Align also settled the remaining ITC action through an agreement with ClearCorrect that was contingent on the appeal decision. With the appeal ruling in its favor this week, ClearCorrect has effectively resolved three of Align’s four litigations and expects to successfully resolve the final case.

YouTube as a patient-information source for root canal treatment




To assess the content and completeness of Youtube as an information source for patients undergoing root canal treatment procedures.


YouTube ( was searched for information using three relevant treatment search-terms (‘endodontics’, ‘root canal’, ‘root canal treatment’). After exclusions (language, no audio, >15mins, duplicates), 20 videos per search-term were selected. General video assessment included duration, ownership, views, age, likes/dislikes, target-audience and video/audio quality, while content was analyzed under 6 categories (‘aetiology’, ‘anatomy’, ‘symptoms’, ‘procedure’, ‘postoperative course’, ‘prognosis’). Content was scored for completeness-level and statistically analyzed using ANOVA and post hoc Tukey's test (p<0 .05="" p="">


To obtain 60 acceptable videos, 124 were assessed. Depending on the search-term employed the video content and ownership differed markedly. There was wide variation in both the number of video views and ‘likes/dislikes’. The average video age was 788 days. In total 46% of videos were ‘posted’ by a dentist/specialist source; however, this was search-term specific rising to 70% of uploads for the search ‘endodontic’, while laypersons contributed 18% of uploads for the search ‘root canal treatment’. Every video lacked content in the designated 6 categories, although ‘procedure’ details were covered more frequently and in better detail than other categories. Videos posted by dental professional (p=0.046) and commercial sources (p=0.009) were significantly more complete than videos posted by laypeople.


YouTube videos for endodontic search-terms varied significantly by source and content and were generally incomplete. The danger of patient reliance on YouTube is highlighted, as is the need for endodontic professionals to play an active role in directing patients towards alternative high-quality information sources.

Anti-Caries Effect of Arginine-Containing Formulations in vivo: A Systematic Review and Meta-Analysis

Table of Contents
Vol. 49, No. 6, 2015
Issue release date: Published online first (Issue-in-Progress)



Objective: To assess the anti-caries effect of arginine-containing formulations in vivo on caries lesions compared with fluorides or placebo. Methods: Randomized or quasi-randomized human clinical trials wherein arginine was delivered by any method were considered. The MEDLINE, Web of Science, EMBASE, Cochrane Library, and CBM databases were searched to identify relevant articles published up to December 2014. Grey literature was also searched. Two authors performed data extraction independently and in duplicate using data collection forms. Each included study was assessed using the Cochrane risk of bias assessment tool. Results: Of the 470 studies screened, 31 full articles were scrutinized and assessed for eligibility. Ten studies (n = 15,546 participants) were selected for final inclusion. The meta-analysis results (n = 7 studies) demonstrated a synergistic effect of arginine when used in conjunction with fluoride on early coronal and root caries compared with placebo or fluoride alone. No specific side effects related to arginine usage were identified. Conclusions: When used in combination with a calcium compound and fluoride, arginine potentially provides a superior anti-caries effect compared with matched formulations of fluoride alone. However, the level of evidence was downgraded because of risks of bias and potential publication bias. In the future, more high quality, non-industry-supported clinical studies in this research area are required before any definitive recommendations can be made.

Comparative evaluation of sealing ability and microstructure of MTA and Biodentine after exposure to different environments

Clinical Oral Investigations
pp 1-6
First online:




The aim of this study was to evaluate the sealing ability and morphological microstructure of Biodentine in comparison to ProRoot mineral trioxide aggregate (MTA) after storage in an acidic environment.

Materials and methods

Biodentine and ProRoot MTA were prepared and packed into the canal lumen of dentin disks. Twenty specimens of each material were further randomly divided into two groups according to the storage media: group A: materials with saline as storage medium; group B: materials with citric acid buffered at pH 5.4 as storage medium. The sealing ability was evaluated at 1, 3, 6, and 24 h and 1 or 3 months, using a fluid transport model for quantitative analysis of endodontic microleakage. The morphological microstructures of the materials were also evaluated using scanning electron microscopy.


During the first 24 h, MTA showed greater fluid transport values than Biodentine in both environments. At the 3-month measurement, when the materials were stored in saline, MTA showed greater ability to prevent fluid movement than Biodentine (p < 0.0001). However, when the materials were stored in an acidic environment, no statistical significant difference was found after 3 months. After storage in saline, both materials showed an uneven crystalline surface with similar hexagonal crystals. The microstructure of Biodentine changed after exposure to citric acid, showing a relatively smooth surface with more spheroidal crystals.


The exposure to an acidic environment, within the limits of this study, seems to result in morphological changes of Biodentine in a different manner than MTA. MTA shows good ability to prevent fluid movement over time, in both environments. The ability of Biodentine to prevent fluid movement over time was enhanced in the acidic environment.

Clinical relevance

The findings of the present study could imply that both materials are indicated for use in an acidic environment.
