Jordan Sigale Quoted in Bloomberg BNA Article re Apple v. Samsung
Posted Sep 23, 2015 at 9:16 am See More

Bloomberg BNA reported on September 18, 2015, that “Samsung must remove or replace Apple-patented features from its smartphones and tablets, according to a Sept. 17 decision by the U.S. Court of Appeals for the Federal Circuit (Apple Inc. v. Samsung Elecs. Co., Fed. Cir., 2014-1802, 9/17/15).”  The court was divided in this ruling, offering three separate opinions.  The majority, however, held that Apple had shown a connection between the patented feature and downstream sales, noting that the patent features were important to consumers.  In a concurring view, Judge Jimmie V. Reyna “said that a patentee’s reputational harm will “certainly” occur “when customers find the patentee’s innovations appearing in a competitor’s products.””

Jordan Sigale said, “The real crux of the majority’s opinion is its holding that to prove irreparable harm the patentee need not prove in a multi-featured product that the infringing feature was the sole feature driving consumer demand for the product.”

Disputes between Apple and Samsung include two cases tried in the U.S. District Court for the Northern District of California on different sets of patents, according to Bloomberg.  “The U.S. Supreme Courot in eBay, Inc. v. MercExchange LLC, 547 U.S. 388, 78 U.S.P.Q. 2d 1577 (2006) (72 PTCJ 50, 5/19/06), chastised the appeals court for defaulting to an injunction for patent infringement, absent a “sound” reason for denying it.”   In the case at hand, “[u]nderlying the three opinions is a dispute in the Federal Circuit about injunctions generally.” 

Sigale put the differing views in perspective, as to how eBay addresses the circumstances of cases like this specifically.  “As much as the Supreme Court made clear in eBay that injunctive relief should not automatically follow every finding of patent infringement, the Federal Circuit made clear today in Apple IV that not every infringing feature in a multi-feature product should receive an automatic pass on irreparable harm either.”

Bloomberg noted that the Federal Circuit, should it decide to take the case en banc, “may have more to resolve than what to do with injunctions on multi-featured products specifically.  The court’s decision vacates the denial of a permanent injunction and remands for further proceedings.”

Dunlap Codding Director Jordan A. Sigale Quoted in Law360 on Michael Jordan Verdict
Posted Aug 27, 2015 at 11:42 am See More

Jordan Sigale was quoted in a Law360 article by Zachary Zagger on August 24, “Jordan Verdict A Warning For Advertisers On Image Use.”  The article commented on the verdict in Jordan et al. v. Dominick’s Finer Foods, LLC, in which lawsuit Jordan was awarded $8.9 million in damages by a jury “in a trial over a full-page advertisement in Sports Illustrated taken out in 2009 by former Chicago-area grocery chain Dominick’s Finer Foods LLC, now owned by Safeway Inc., without the superstar athlete’s approval.”  The ad offered a coupon for $2 off a steak and depicted and congratulated Jordan, saying “you’re a cut above the rest.”  Jordan’s likeness was used without his approval and he testified in trial that he does not take less than $10 million for advertising deals using his image or likeness, and that he would not have approved this use at any price because it was not in keeping with his strategy.

Sigale was quoted as saying the case forced the jury to decide what the true fair market value of the ad was in 2009 and that it says a lot about how a “jury of our peers” views the way in which we compensate people for their right of publicity.  He went on to observe, “While this jury was clearly comfortable with the notion that some people’s right of publicity can be extremely valuable, it wasn’t willing to completely side with Mr. Jordan.”  Dominick’s had argued that the fair market value was closer to $100,000.  Sigale noted that the jury didn’t award Jordan the full $10 million, but also didn’t go as low as Dominick’s sought.

Emily Campbell Quoted in Bloomberg BNA’s Patent, Trademark & Copyright Journal on Trademarks and Likelihood of Confusion
Posted Aug 11, 2015 at 13:54 pm See More

On August 7, Bloomberg BNA covered DC Comics v. Gotham City Networking, Inc., T.T.A.B., No. 91194716, 7/17/15.  The case involves a trademark application filed by Gotham City Networking Inc. for “Gotham Batmen” with a stylized bat-like logo to be used in networking referral services and “entertainment in the nature of amateur softball games.”  According to Bloomberg, “DC Comics, which owns the rights to Batman and numerous trademarks related to the superhero, opposed the registration on dilution and likelihood of confusion grounds.”  The Trademark Trial and Appeal Board ruled on July 17, that the use of the name “Gotham Batmen” was likely to cause confusion with a number of different marks owned by DC Comics.

Administrative Judge Jyll Taylor provided a dissenting opinion, noting that DC Comics had failed to establish that “Batman” was a famous mark, having not proven the connection between DC and Warner Bros. Studies.  According to BloombergBNA, “[t]he majority had found “Batman” to be famous, largely because of the films.

Gotham City argued that its trademark constituted a parody.  Dunlap Codding Shareholder Emily Campbell was quoted as saying that “for a parody defense to succeed in trademark law, the parodist has to walk a “fine line” between resembling the parodied mark and making a point…. [A] poster of a pregnant woman wearing a Girl Scout uniform with the Scouts’ slogan “Be Prepared” written underneath qualified as an example of an outrageous joke that worked as a trademark parody.”  She explained that the “Batman” –  “bat men” softball joke was not nearly as obvious and therefore did not bode well for Gotham City’s chances that its mark was a parody and would not cause confusion.

Campbell also said that Judge Taylor’s concerns were valid, and the majority’s famous mark analysis could be an issue on appeal.  “The dissent is interesting because there does seem to be a hole in the evidence.  The majority filled in the blanks to come to the conclusion that we all recognize the Batman name, but I think to adhere to the law [the board needed to make a fuller analysis.]”

Dunlap Codding Director Jordan A. Sigale Quoted in Articles Analyzing the U.S. Supreme Court’s Ruling in Kimble v. Marvel
Posted Jun 25, 2015 at 12:06 pm See More

Jordan A. Sigale was quoted in Donna Young’s recent article in Scrip Intelligence, “Patent ‘superpowers’ time limits upheld:  Biopharma implications.”  Young wrote that Kimble v. Marvel  “may help patent holders and those that enter into licensing rights deals, including biopharmaceutical makers, better understand and be more aware of a nearly half-century old case law rule.”  

The U.S. Supreme Court, in a split decision, declined to overturn the 1964 standard set in Brulotte v. Thyswhich ruled that patent holders cannot demand royalties for the use of their inventions after the patent terms have expired. 

Sigale said, “Big biopharmaceutical firms are well-represented in patent law and intellectual property matters, so they already know their way around the Brulotte rule….If anything, the Supreme Court’s ruling in the Marvel case makes it clearer the Brulotte rule is narrow and that there are ways to draft around it….But for those who are unsophisticated about Brulotte, the opinion is unfortunate….It would be much better to knock out this rule.  It doesn’t make economic sense…and any standard that gives the advantage to those who can afford the best legal representation is bad for society.”

 Ryan Davis, writing for Law360, on June 22, 2015, also quoted Sigale.  Davis wrote, “The Kimble case arose because neither party knew about the [Brulotte] rule when Marvel agreed to license Kimble’s patent for use in a Spider-Man Web Blaster toy in perpetuity.”  Sigale was quoted as saying, “The decision explains that the Brulotte rule really is as narrow as we thought it was….If you make it clear there are no royalties for the patent after it expires, you can do anything you want.”  

“Sigale said it was helpful that the court expressly gave its blessing to later payments of royalties accrued during the life of the patent,” said Davis.  Sigale said, “Before today, people were a little nervous that the court would say that’s just putting form over substance.”

Dunlap Codding Senior Associate Julie L. Langdon Quoted in Law360—“6 Ways Associates Are Falling Short”
Posted Jun 2, 2015 at 13:36 pm See More

Julie Langdon was quoted by Cara Salvatore in an article published by Law360 on June 1, 2015, entitled “6 Ways Associates Are Falling Short.”  The article noted the following ways associates are stumbling and offered steps to improve:

  • They Aren’t Visible Enough
  • They Don’t Take Ownership
  • They’re Not Thorough
  • They’re Not Friend Material
  • They Don’t Know How to Talk on the Phone
  • They Don’t Sow the Seeds for Business Development

Discussing ownership, Langdon noted that it was important to follow up relentlessly and to know what to do when mistakes occur.   When they do, as they inevitably will,  it’s important to own the problem quickly and take steps to correct it.  “Unfortunately, it happens:  A document that was supposed to be filed under seal that was, by mistake, filed publicly, and you’re calling the clerk at 8 a.m. the next morning…’take this off the docket.’”  She went on to note, “All things are fixable.”


DC On Film Row

About DC on Film Row

DC on Film Row is a free event space open to everyone in our community.

We like to say that the space is a “home for creatives and innovators, home builders and the homeless, celebrators and the celebrated” so people understand that we are inclusive and want everyone from throughout our community using our space.

Our goal is to celebrate the incredible diversity of creativity, innovation, and passion within Oklahoma City and to provide a venue—free of charge—to those groups and individuals working to bind us all together and make our home a cooler and better place. No strings attached—no extensive rules to follow. We simply ask that all of our neighbors be honored and that all viewpoints be respected. Our criteria for use is simple: If the event, group, or meeting is something which strengthens our community and brings us all together, the space is available for use.

The space has hosted everything from charitable fundraisers to an underground nightclub party to celebrate Canterbury Choral Society’s 45th anniversary season. We host dinners for the OKC homeless population most Monday evenings where upwards of 250 people are served—we provide the space and soft drinks and a local church provides the food. We’ve hosted university planning retreats and monthly local rock concerts.

Every Wednesday, we open up the courtyard for lunch, invite a local food truck to set up outside our gates, and welcome our downtown neighbors into the space for a bit of socialization.

Our never-ending soda fountain seems to be the biggest hit with some of our neighbors while others spend time playing pool or simply chatting about what is happening on the weekend.

For October we turn the space into a haunted house and invite the neighborhood children to come out and trick-or-treat.

Got an idea for how to use the space? Just ask us – we’re almost certain to say yes!

Who we are.
