Dunlap Codding Shareholder Doug Sorocco Quoted Extensively in MacNewsWorld on the Apple/Google Kodak Patent Deal
Posted Dec 17, 2012 at 14:21 pm See More

Doug Sorocco was quoted extensively in MacNewsWorld on December 12, 2012, in an article by Rachelle Dragani, “Apple Cozies Up to Google for Kodak Patent Deal.”  

Apple’s rumored odd-couple alliance with Google to buy Kodak patents is primarily a defensive opportunity for both companies to gain access to a broad portfolio and share in the underlying costs, said patent attorney Douglas Sorocco. “Both parties are looking to insulate themselves from patent infringement claims if a third party got their hands on one or more of the patents.” 

Normally, that defense could be especially helpful for Apple, which is fighting Samsung in courtrooms around the world. In the Kodak patent buy case, however, Apple’s partnership with Google could be doing more for Samsung than Apple might like, suggested Sorocco. 

“Generally, this move probably is more helpful to Samsung, as they work closely with Google and the Android operating system,” he pointed out.  Still, the move makes sense from both sides, Sorocco continued. As much attention as Apple’s high-profile battle with Samsung gets, it’s not the only patent war the company is waging. Teaming up with a noted rival to increase its portfolio could be a move that ultimately saves precious legal resources in the future. 

“My read is that this is primarily a defensive opportunity for both Apple and Google to gain access to a broad portfolio of technology patents and share in the underlying costs,” Sorocco observed. 

“Both companies get what they want — freedom from suit and potential bargaining chips — and share the cost of doing so,” he pointed out. “It’s a pretty smart strategic and financial decision and doesn’t significantly impact the underlying disputes the companies have with one another on their core technologies.”

Posted Oct 22, 2012 at 8:07 am See More

The Journal Record recently reported on Dunlap Codding’s new offices in the works at 609 West Sheridan in the Film Exchange District of Oklahoma City.  Reporter Brianna Bailey wrote, “With the help of the commercial construction company Design+Build Group, local intellectual property firm Dunlap Codding is transforming a 1920s-era industrial building in the Film Exchange District into a headquarters for its growing law practice.”  The firm’s shareholders purchased the 14,250-square-foot brick building in December. 

Douglas Sorocco, one of the firm’s shareholders, was quoted as saying the area was a good fit for the firm.  “Since we work with very creative and innovative people – artists, scientists and musicians – we wanted a space that kind of reflected that creativity and innovation we see in our clients,” he said.  Working closely with Design+Build Group, the firm is remodeling the industrial space—originally built in the 1920s—to include more than 40 new windows and skylights in the brick building.  The firm has also planned a spacious outdoor courtyard for employee use and anticipates making the space available for community creative events.  The firm also anticipates expansion and is building in the infrastructure for an eventual second and third floor.

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.
