Deere & Company (NYSE: DE), which also goes under the brand name of John Deere, is an American corporation headquartered in Moline, IL, which develops and manufactures machinery and heavy equipment for agricultural, forestry, construction and other industries.
John Deere is involved in a great deal of innovation related to its heavy machinery, even in the field of data analytics, partnering with cloud computing company SAP to improve information technologies for its heavy machinery and equipment. The corporation is regularly recognized for its innovations, including the recent announcement of a trio of John Deere inventions being recognized at the 2015 SIMA Innovation Awards. In November of last year, the company also received an award from the Farm Business Cream Awards, which honor advancements in the dairy industry, for a sensor system that quickly measures organic material within crops.
Earnings reports for Deere & Co.’s fourth quarter of 2014 indicate some difficulty in growing revenues as the company reported quarterly net income of $649.2 million, compared to $806.8 million from the same period in the previous year. Interestingly, John Deere’s expenditures in research and development actually increased year-over-year, from $405.2 million during 2013’s fourth quarter to $412.1 million in the fourth quarter of 2014. Low agricultural commodity prices in recent months, which have hurt the ability of farmers to make capital purchases, may contribute to a lower than expecting earnings report for 2015’s first quarter, which the company will release in the coming days.
Deere & Co. didn’t place among the IFI Claims Top 50 U.S. patent recipients for 2014. During 2013, the company ranked 142nd overall among worldwide entities seeking patents from the U.S. Patent Institution; John Deere earned 233 U.S. patent grants in that year, an increase of 22 percent over the company’s previous year totals. Our research using the Innography patent analysis service showed us that Deere & Co. received another 233 U.S. patents during 2014. A heavy focus on control units and data processors confirms greater activity in information technology developments, although continue to Deere bread-and-butter innovations such as seeing electric motors, work machines and seed vehicles being heavily reflected in the company’s 2014 patent grants.

Patent Applications of Note: From Convertible Mower Decks for Mulching to Particulate Filters for Biofuel/Diesel Fuel Blends
We noticed a number of John Deere patent applications filed in recent months that reflect the development of mowing and mulching machines. U.S. Patent Application No. 20140331634, which is titled Convertible Mower Deck With Mulch on Demand Actuator, relates to a mower deck which can be more easily converted from a mulching mode to a discharge mode. The convertible mower deck claimed here has a deck with a plurality of cutting chambers, each chamber having a rotary cutting blade and one chamber having a side discharge opening, a plurality of pivoting gates between each of the cutting chambers, a pivoting side discharge door between the side discharge opening and one of the chambers and a mulch on demand actuator with a switch in the operator station which causes a pivot control plate to rotate and move linkages attached to the pivoting gates and the side discharge door. This improved convertible mower deck allows an operator to initiate or stop a mulching mode without reaching outside of the operator station to access a control. Convertible mower decks are also the subject of U.S. Patent Application No. 20140318099, entitled Multi-Blade Mower Deck With Mulch/Side Discharge Conversion. The multi-blade mower deck protected here contains a mulch gate mounted under the mower deck and extending rearwardly along a portion of the perimeter of the first cutting chamber, a mulch gate lever that pivots the mulch gate between a mulching position and a side discharge position and a baffle mounted under the mower deck and extending forwardly and blocking a portion of the flow passage from the first cutting chamber. The innovation results in a multi-blade mower deck which is easy to install, is low in cost and maintains good mulching and side discharge qualities.
Although John Deere’s vehicular technologies are related to work vehicles and not consumer automobiles, we still found a few more vehicular technologies expressed by company patent application filings that we felt were worth sharing. Information technology and data systems for John Deere vehicles for displaying important messages are the focus of U.S. Patent Application No. 20140325419, filed under the title Virtual Terminal Display for a Vehicle.
