Lex Machina Q4 2017 End of the Year Litigation Update

In the final quarter of 2017, a total of 981 patent cases were filed in U.S. District Courts, a 1.3% decrease over the previous quarter’s total of 994 cases.  Cases filed in the calendar year 2017 (4,057 cases) represent a decline of 10.3% over 2016 (with 4,529 cases). Despite the decline, Figure 2 shows that 2017 continues the pattern of relatively consistent monthly totals that has persisted since the dramatic spike in 2015 (caused by the end of Form 18).

Patent Litigation Trends in the Three Months after T.C. Heartland

This blog post focuses specifically on patent litigation trends; for a broader discussion of other litigation trends in Q3, see our update here. On May 22, 2017, the Supreme Court issued its opinion in T.C. Heartland, holding unanimously that, under 28 U.S.C. § 1400(b) (the statute governing venue in patent suits), a domestic corporation “resides” only in its state of incorporation. Since that landmark decision, patent case filings trends have responded dramatically:  the number of cases filed in the Eastern District of Texas has significantly declined and been overtaken by the number of cases filed in the District of Delaware. Fig. 1:  Top districts by patent cases filed 2014-2017 Q3 Looking at a window of 90 days on either side of the T.C. Heartland, the change is stark.  Before T.C. Heartland more than twice as many cases were filed in E.D. Tex. as D. Del.; but afterwards, it’s less than half.  The number of cases filed outside of the top two districts is very similar.   Fig. 2:  Cases filed 90 days before and after T.C. Heartland Viewing the filing numbers on a week-by-week basis shows that the trend towards Delaware is not the result of a single period of [...]

SCOTUS Decides TC Heartland Case

On Monday, May 22, 2017, the Supreme Court issued a slip opinion in the case TC Heartland LLC v. Kraft Foods Group LLC (Dkt. No. 16-341). The court unanimously* held that, under 28 U.S.C. § 1400(b) (the statute governing venue in patent suits), a domestic corporation “resides” only in its state of incorporation, consistent with its ruling in an earlier case, Fourco Glass Co. v. Transmirra Products Corp., 353 U. S. 222 (1957).  The Court rejected arguments that the general venue statute, 28 U.S.C. § 1391(c), which was amended post-Fourco and twice since § 1400, overrode the definition of residence in § 1400(b) with a more expansive one that made residence coextensive with personal jurisdiction.  In doing so, the Court overruled the Federal Circuit’s decision in VE Holding Corp. v. Johnson Gas Appliance Co., 917 F. 2d 1574 (1990). * Justice Gorsuch did not participate in the decision. What Does That Mean and What Did TC Heartland Change? Why is a seemingly technical matter of statutory interpretation so significant? Before this decision, a plaintiff looking to sue a corporation for infringing its patent could choose any jurisdiction where the defendant did significant business.  Large corporations doing business all over the [...]

2017 First Quarter Litigation Update

Lex Machina Q1 2017 Litigation Update Patent litigation District Court 938 patent cases were filed in the first quarter of 2017.  This was the lowest per-quarter filings of any quarter since 2011 Q3 (although just barely - there were 963 cases filed in Q1 of 2016).  From last year’s average of 1130 cases per quarter, Q1 is down about 17%. Despite the low volume, case filings rose month-by-month during the first quarter of 2017 (see Fig. 2), and remain within the pattern established in 2016.  Historically, the first quarter has often been lower than the year’s final average. The dramatic spike in 2015, apparent in Figure 2, was caused by the end of Form 18. Fig. 1:  Patent cases filed, 2011 - 2017 Q1, by quarter   Fig. 2:  Patent cases filed, 2014 - 2017 Q1, by month     More patent cases (33% of those filed in 2017 Q1) were filed in the Eastern District of Texas than in any other jurisdiction.

The District of Delaware remained the [...]

The fourth quarter represents a slight increase over the third quarter’s 1,126 cases, but overall litigation in 2016 has declined by a moderate 22% from 2015 (when 5,823 cases were filed).  Month by month, 2016 has been relatively consistent compared to the dramatic spike in 2015 caused by the end of Form 18. Fig. 1:  Patent cases filed, 2011 - 2016, by quarter Fig. 2: Patent cases filed, 2011-2016, by year Fig. 3:  Patent cases filed, 2014 - 2016, by month The majority of patent litigation filed in 2016 (36.4% of cases) was filed in the Eastern District of Texas.  The District of Delaware remained the second most frequently used jurisdiction, with just over 10% of cases filed in 2016.   The percentage of cases filed in the Eastern District of Texas has also been increasing, from around 30% in the first quarter, to 40% in the fourth quarter of 2016.

2016 Third Quarter Litigation Trends

Patent Litigation District Court In the third quarter of 2016, plaintiffs filed 1,127 patent cases.  This total represents an decrease over Q2 (1,289 cases) of 12.6%, but is still higher than the Q1 2016 (960 cases). Looking at the months in the second second quarter more closely (Fig. 2), September (310 cases) was slower than both July (416 cases) and August (401 cases).  Relative to the first three quarters of previous years, 2016 looks to be the slowest year since 2011 (Fig. 3). The proportion of total new filings made in the Eastern District of Texas held nearly steady in Q3 at 35.4% - down slightly from 37% in the second quarter but up from the first quarter (30%) (Fig. 5).  In 2015, for comparison, the district had 43% of the patent cases filed.

2016 Second Quarter IP Litigation Trends

Patent Litigation District Court In the second quarter of 2016, plaintiffs filed 1,282 patent cases.  This total represents an increase over Q1 (958 cases) of 33%, but remains below the 2015 average of 1456 cases per quarter.   Looking at the second quarter more closely (Fig. 2), more than 450 cases were filed in both April and June, while May saw only 370 cases.  Patent litigation levels appear to have stabilized after the spike-and-trough pattern (seen in November 2015 through February 2016) caused by the rule change on Form 18. The Eastern District of Texas saw an uptick in its proportion of total new filings to 37% in the second quarter of 2016 against the first quarter (30%).  In 2015, for comparison, the district had 43% of the patent cases filed.   Fig. 1:  Patent cases filed, 2012 - 2016 Q2, by quarter   Fig. 2:  Patent cases filed, 2014 - 2016 Q2, by month   Fig. 3:  Top districts by patent cases filed, 2012 - 2016 Q2   Fig. 4:  Top districts by patent cases filed, 2016 Q2     The Patent Trial and Appeal Board Covered Business Method (CBM) reviews have remained steady, but the number of Inter [...]

2016 First Quarter IP Litigation Trends

Patent Litigation District Court In the first quarter of 2016, 955 patent cases were filed.  This number represents a decline from the level of litigation seen over the last few years - a quarterly low not seen since 2011.   Looking at the quarter more granularly (Fig. 2), shows that the first two months of the quarter were similar to December, while March saw an increase.  Given the spike which occurred in November, it’s possible that many of the cases which would otherwise have been filed in the months of December, January and February were shifted up into November.   The Eastern District of Texas saw a marked decrease in new filings in the first quarter of 2016.  While the district had 43% of the patent cases filed in 2015, in the first quarter of 2016 the percentage dropped to 30%   Fig. 1:  Patent cases filed, 2012 - 2016 Q1, by quarter   Fig. 2:  Patent cases filed, 2014 - 2016 Q1, by month   Fig. 3:  Top districts by patent cases filed, 2012 - 2016 Q1   Fig. 4:  Top districts by patent cases filed, 2016 Q1     The Patent Trial and Appeal Board The first quarter [...]
