The following blog post is courtesy of our sister blog, NorCal IP.

Usually, one benefit of being a plaintiff is deciding in what forum to pursue litigation.  Generally, even a foreign-based plaintiff may pursue litigation in a U.S. forum where a defendant may be found or in which there is a substantial connection to the litigation.  There are, however, limits on a plaintiff’s choice of forum, and a recent decision in Tapgerine LLC v. 50Mango, Inc. demonstrates that pushing those limits may result in sanctions.


ECONOMIC ESPIONAGE AND PROTECTING TRADE SECRETS: Ninth Circuit Holds That Reasonable Measures to Guard Technology are Sufficient

How can you protect your trade secrets from a vast and well-concealed international effort to steal those secrets? What constitutes a “reasonable” effort to protect that information where at least one competitor may already have the information?  The Ninth Circuit recently opined on these matters in the ongoing saga of U.S. v. Liew.

In 2014, Walter Liew and his company, USA Performance Technology, Inc., were convicted of multiple offenses, including claims under the Economic Espionage Act and conveying misappropriated trade secrets to a third party. The trade secrets related to DuPont’s technology for producing titanium dioxide, which is used in a wide range of products such as paint and Oreo cookies. READ MORE

No Way Around It: SB 1241 Further Restricts Non-Compete Agreements For California Workers

Companies often seek to protect their trade secrets by requiring employees to sign non-compete agreements. California law invalidates such provisions except in very limited circumstances. See Bus. & Prof. Code §§ 16600 et seq. With the recent passage of a new statute, the ability of employers to enforce such agreements against California employees is more restricted than ever.   READ MORE

Founding Fathers (or cases) of Trade Secret Law: A Look Back in Celebration of Independence Day

Over the last few weeks, TSW has reported extensively on the first few cases brought under the new Defend Trade Secrets Act. But, given our recent celebration of our nation’s birthday and the day Will Smith saved the planet from alien attack, TSW takes a brief look back at the foundation and birth of trade secret law in the United States.

Proving “Loss” Under the Economic Espionage Act – Not Always Straightforward

The Obama Administration’s focus on criminal trade secret prosecutions under the Economic Espionage Act (EEA) highlights the legal complexities at the murky intersection between criminal and civil jurisprudence in trade secrets cases. As we previously discussed, when it comes time for sentencing, determining the “value” of the stolen trade secrets is often difficult—and courts have applied different valuation models. READ MORE

Throwback Thursday: Why Trade Secret Theft Isn’t Just a Digital Problem And What Businesses Can Do About It

With stories of cyberattacks and data breaches on a seemingly endless loop, businesses and governments have been doubling down on their efforts to protect digital information and assets.  But, in some industries, the greatest threat might still be a pair of quick hands.  For instance, in the restaurant industry, opening the kitchen doors to a new employee creates real risks.  As we’ve discussed, sometimes the decision whether to print or download can have major legal ramifications.  And with computer forensics technology growing in leaps and bounds, sometimes an old-school paper trail might be more enticing to would-be perps than a digital one.  That said, the FBI has a track record of turning up bags of shredded documents in grocery store dumpsters.

Will We See Federal Trade Secret Legislation Passed This Year?

In January of this year, we noted that trade secret protection has lately been on the minds of lawmakers in Washington, and that federal trade secret legislation was very close to being enacted.  While nothing is pending at the moment, we can expect renewed efforts similar to two bills that were introduced in Congress last year – one each in the Senate and House.  In anticipation of such efforts, we thought it would be useful to review what happened in 2014.

Settlement Reached in Wyoming Fracking Disclosure Lawsuit: Heavier Burden of Proof for Companies Claiming Trade Secret or Confidentiality Protections

As we’ve previously discussed, a patchwork of state regulations requiring disclosure of chemicals used in fracking have been enacted by several states in recent years.  One such regulation was by the State of Wyoming.  While environmental groups initially lauded Wyoming’s new rule, the applause was short-lived as the Wyoming Oil and Gas Conservation Commission began granting trade secret exemptions that prevented disclosure of this information to the public under the state public records act.  This led the environmental groups to sue the Commission.  After nearly three years of litigation, including an appeal to the Wyoming Supreme Court, the parties reached a settlement that was approved by the state district court late last month.


WORLD SERIES EDITION: These Trade Secrets Are Going, Going, Gone

Ah, October: the time of crisp fall air, brightly colored leaves, and pumpkin spice-flavored everything. And, of course, the World Series quest that can unite a city—or, in the case of Orrick’s San Francisco and Washington, D.C. offices, give rise to a friendly wager (sorry, D.C.!). In honor of the baseball playoffs, we take a look at some trade secret issues related to our national pastime.
