VINEYARD INVESTIGATIONS, Case No. 1:19-cv-01482 JLT SKO

Plaintiff, ORDER DIRECTING THE PARTIES TO v. SUBMIT SUPPLEMENTAL BRIEFING E. & J. GALLO WINERY, Defendant. The Court has completed a detailed review of the record of the case, including prior orders and briefs. After considering the patents-in-suit and the relevant technologies in more detail, the Court finds that its decision-making will benefit from supplemental briefing. It is well-established that direct, “literal infringement requires that each and every limitation set forth in a claim” is found in an accused product or is performed by the direct infringer. See Frank’s Casing Crew & Rental Tools, Inc. v. Weatherford Int’l, Inc., 389 F.3d 1370, 1378 (Fed. Cir. 2004) (citation omitted).1 In regard to the parties’ dispute over the “sensors associated with” limitation, it is undisputed that Plaintiff identified three types of sensors used in Defendant’s accused systems: flow meters, pressure sensors, and soil moisture sensors. (Doc. 172-1 at 20; Doc. 180-1 at 66 (undisputed fact No. 88).) As the Court explained in its claim construction order, while a sensor may be associated

1 The parties do not appear to argue over the doctrine of equivalents (“DOE”) or the reverse DOE. with a “plurality of plants,” the asserted claims do not read on (i.e., cover) systems or methods where a single sensor is associated with a “field, region, or plot of land.” (Doc. 94 at 29–35.) From this, Defendant appears to advance two interrelated arguments. First, Defendant contends that because its system uses one soil moisture sensor per 650 vines or more, (Doc. 172-1 at 20; Doc. 180-1 at 29 (undisputed fact No. 31)), each of its soil moisture sensor is not associated with individual plants or localized plant groups, but with a “field” or “a plot of land,” (see Doc. 172-1 at 19–20, 22–24). As such, Defendant maintains that none of its systems infringes on the asserted claims. Second, Defendant appears to argue in the alternative that even if a soil moisture sensor is associated with 650 plants, it is also associated with a “field,” a “homogenous agricultural area,” or a “plot of land,” (see Doc. 172-1 at 20, 23 & n.16); the latter three are what Hall teaches.2 Accordingly, Defendant may be trying argue that if the claims-in-suit read on its systems— wherein each moisture sensor is associated with a “field” or a “plot of land”—as to prevent Defendant from practicing prior arts like Hall, the asserted claims are necessarily invalid. (See id. at 24.) This is because a patent claim which “exclude[s] the public from practicing the prior art[] . . . is anticipated, regardless of whether it also covers subject matter not in the prior art.” Atlas Powder Co. v. Ireco, Inc., 190 F.3d 1342, 1346 (Fed. Cir. 1999) (citing Titanium Metals Corp. of Am. v. Banner, 778 F.2d 775, 781 (Fed. Cir. 1985)); see also Graham v. John Deere Co. of Kansas City, 383 U.S. 1, 6 (1966) (“Congress may not authorize the issuance of patents whose effects are to . . . restrict free access to materials already available.”). However, the parties do not clearly articulate their positions regarding the moisture sensors, especially regarding the meaning—or the size—of a “field,” a “homogeneous agricultural area,” or “a plot of land.” The Court therefore requests the parties to submit supplemental brief clarifying their positions and arguments, as detailed below. Next, with respect to the flow meters and pressure sensors, Plaintiff argues that they are 2 The Court notes that the file history of the patents-in-suit clearly shows that the named inventor deliberately distinguished away Hall. (Doc. 94 at 34.) In particular, the named inventor argued that Hall teaches, inter alia, the use of direct sensors that “are not localized to the plant level.” (Doc. 70-10 at 73 (citation omitted).) Indeed, the named inventor expressly quoted portions of Hall stating that “a homogeneous agricultural area” may include, for “sensors” within the meaning of the patents-in-suit, (Doc. 185 at 18), even though they do not measure anything about actual plant/field conditions, as Defendant correctly points out, (Doc. 172-1 at 21).3 Plaintiff further contends “there is no requirement” that flowrate and pressure data from the sensors must be “entered into an irrigation schedule.” (Doc. 185 at 16.) Therefore, under Plaintiff’s theory of infringement, a water sprinkler system equipped with little more than a generic process control panel/computer, basic flow/pressure sensors, and passive water emitters might infringe, for instance, claim 2 of U.S. Patent No. 6,947,810. See col. 7 ll. 3–6 (“[T]he emitters can be passive[;] for example, they can be simple through-holes sprinkler heads so that they are always ‘on’ for all dispensing.”). If so, claim 2 may be anticipated or obvious,4 which poses a claim-construction issue because claims should be construed to preserve validity. (See Doc. 172-1 at 24 (citing Phillips v. AWH Corp., 415 F.3d 1303, 1327 (Fed. Cir. 2005).) The Court has similar concerns for all the other asserted claims and, therefore, believes that it may benefit from additional briefing on (i) the risks of anticipation and obviousness and (ii) how the asserted claims should be interpreted accordingly. Defendant’s briefs directly and indirectly allude to 35 U.S.C. § 101 patent eligibility on numerous occasions. (See, e.g., Doc. 172-1 at 7–8 (“It is important to emphasize that in Gallo’s accused experimental vineyards, a human made the core decisions, something humans have been doing for centuries—thinking about the weather, looking at the plants, and deciding when and where to apply water.”); id. at 8 n.3 (appearing to seek “permission to file a short supplemental motion for summary judgment of invalidity of all Asserted Claims under 35 U.S.C. § 101”); Doc.

3 The Court further notes that many of the sensors mentioned in the specification measure plant or field conditions. For example, photodetectors, which measure the amount of sunlight, and temperature sensors are related to weather conditions in the field. (See ’834 patent col. 5 ll. 38–42.) Similarly, soil nutrient and moisture sensors detect local field conditions. (Id. at col. 5 ll. 39–40.) Likewise, leaf wetness detectors, (id. at col. 4 ll. 43–44), and pH probes, (id. at col. 8 ll. 9–11), are directly related to plant conditions. Water flow meters and pressure sensors, however, may not be analogous to the aforementioned sensors—rather, they measure the conditions in an artificial system, at least in the present context.
