Humminbird files Suit Against Lowrance 2024
fishfordollars reply :
Well it finally happened. Johnson Outdoors(Humminbird) filed suit against Navico (Lowrance) for patent infringement today in federal court. Louis Chemi the COO of Navico said that the structure scan will still be sold. Going to be fun to watch this unfold.

I saw where Humminbird was given the patent. It will be real interesting to see how ugly this one gets.
mudkart reply :
It's US patent 7,652,952. Claims 1 and 8 offer Humminbird relatively broad coverage on the SI system, which is true for most patents that are truly innovative (the inventors are given a rather broad scope of patent coverage).
I'm not that familiar w/ the details of the Lowrance system, but unless their SI transducers are well outside the dimensions found in the Humminbird patent claims, it appears to be an uphill battle for Lowrance.
Another option for Lowrance would be to argue the Humminbird patent is invalid, not enabled for the full scope, etc.
Hot Rod reply :
I understand how patents work but it seems pretty asinine to me. 
Wasn't lowrance the first company to invent depthsounders and then graphs/LCD's for the fishing industry mainstream? Seems to me its sort of the pot calling the kettle black, to use a cliche. I mean if it weren't for the original Lowrance would there have even been a Hummingbird? JM.02
Dogface reply :
Lowrance has the down scan feature. Hummingbird does not. I wonder how that will figure into equation.

Humminbird added downscan in a software upgrade this month.
As an Electrical Engineer I was taught that patents for electronics were hard to litigate. Someone can copy your design change a small aspect and the patent can't be enforced because they are technically different. I don't have enought time or desire to research and figure out if HB has a winnable case ;D
I believe Lowrance invented the depth finder in 1956. If they were given a patent it would be good for 20 years. It would have long since expired.

I did not know that. Can it be installed on all of the side scan units?

Yes it can. Go to Humminbird.com and download the update for your unit

I thought it was pretty ironic how Lowrance did a 1 up on Humminbird with the down scan technology and then Humminbird brings it out like "O ya, I guess we could do that too".... and then Humminbird files suit against Lowrance?? Looks like Lowrance could possibly do a counter suit on that technology if they patented it.
fishfordollars reply :
Gonna be a fist fight for sure.

The ironic thing is Lowrance tried to copy the technology because they were losing some of their customers. They did try to one up them by giving the DI with the structure scan, which by the way is sold seperately from the depth finder as an option, and saying how truely unique this system was when H-bird had it out for several years prior. So they add DI at no cost to everyone who had SI units for FREE. You would never catch Lowrance giving anything for free and their service stinks. I switched out my LCX-113 and LCX-28 for a 1197c SI and a 798c si. I will say I could not be happier. I did have an issue with my 1197 wich was my fault by the way and had to send it in for repair. I called and they told me to send it in and told me it would be a quick fix. I expected the usual of they tell you a week and it takes a month. This was not the case with H-bird. I mailed it on Monday and had it back on my doorstep by Friday. I would rate this as excellent customer service.
mudkart reply :
Wayne that pic is eerily similar to images of standing timber we found using the lowrance structure scan on the occoquan rez. Around the same depth too, 'tho sometimes deeper.
Wayne P. reply :
NewAngler, I have the 798ci SI
mudkart, that image was done at Briery Creek Lake.
Hot Rod reply :
QuoteYou would never catch Lowrance giving anything for free and their service stinks.
How about it? I sent a unit in to Navico for repairs back in November and am still waiting for the replacement unit; which I had to pay $200 for cause it was a couple months past warranty. Incedentally it was the second time I had an issue with part of this set-up. the GPS puck went bad the 1st time but under warranty.
The fact that Lowrance service is so bad is enough to make me switch to another brand not to mention the cost difference. >

Thanks Wayne.
I liked the downscan feature of the Lowrance but it was too expensive. Now that HB has the same feature and its a free upgrade it would be a better deal.

My buddy bought a new Skeeter last spring and it came with a Lowrance at the bow and an Eagle at the console. We fished the Potomac in the rain. Both units failed due to water leakage. He had to send both units back. Turns out a lot of people are having the same problems.
He can bearly catch fish on my boat because he is constantly looking at the 798c SI on the console!
It is nice that Humminbird continues to offer support and upgrades to their products. I am really happy with my units.
fishingfourfun reply :
I am thinking about buying the 798. Was the unit hard to learn? My Lowrances are used for depth and temp only. The side imaging looks awesome. Is yours set up at the helm or trolling motor?
Tpayneful reply :
I have mine mounted on the console. I have a two transducers, the original round puck that was epoxied into place by Stratos and the Side Imaging transducer on the transom. I have a Humminbird transducer switch to change between Side Imaging at slow speeds 0-5MPH and the regular puck when I am moving from place to place.
Anyone can learn how to use Side Imaging in a few minutes. Of course I sat down with a pot of coffee and read the owners manual but it really isn't needed to get started.
Just select the SI view, move in a straight line at some speed less than 5MPH and the bottom will scroll on the screen. You can press the arrow pad at anytime and it will stop the screen from scrolling. You can move your pointer to any location on the stopped screen and mark waypoints, zoom in on objects and save pictures of what you found.
I bought my boat on October 23rd and only went out a few times before it got too cold. I have not been back out since November. The only SI settings that I change is the distance to scan out from the boat. It normally does 150 feet on each side but I will shrink it down to 50 - 80 feet so the objects are bigger. Sometimes I will scan only to the right or only to the left to cover the whole screen with an area of interest.
I found these blugill beds on my first trip and brushpiles in a channel on my second trip with the unit.
Wayne P. reply :
fishingfourfun, I have my 798ci SI set up for console and bow. I bought the trolling motor SI transducer, another mount and power cord so I could use it in both places since I fish several electric-only bodies of water also.
I would recommend when/if you get one, order an extra power cord so you can practice with it in Simulator mode without having to be in your boat. I still use mine that way and even did the DI software upgrade with it laying in my lap.
fishingfourfun reply :
Thanks for the advice. I have two boats that I use. I will purchase and extra power cord and tranducer to use on the other boat.I fish the Occoquan Reservoir and the Potomac. That set-uplooks like it will help me find more productive water!

I think this will be a pretty messy suit. Patent infringement is not something I would ever want to deal with . They could lose millions.
Tpayneful reply :
Based on the serious leakage issues and terrible customer service, I wouldn't even concider Lowrance.
I have seen the side by side comparison and am not convinced that the settings are set equally.
I Love BassResource reply :
leekage issues have been widely acknowleged as resolved. The CS issues can be noted as horrid on both sides of the house, so pick your poison.
I'm sure the bird's are great units, but lets not dip into denial. The current Lowrance offerings are fresh, while the bird imaging has a bit of age. When/if hb decides to brush things up, I"m sure image quality will be equal.
farmpond1 reply :
If Lowrance simply reverse engineered the Humminbird product, than yes, I suppose a suit is reasonable. But if what is depicted on the screen is arrived at by a different solution, than no, it's not. Since sonar all shares some commonalities, it's the particulars which are important. It probably requires some pretty smart engineers to make those distinctions. What makes me nervous is when it's left up to jurors to decide complicated technical matters. In the court of public opinion, it usually comes down to which product joe layperson is most loyal to.

I checked out the images. Looks to me like the humminbird image was not as light, but the contrast level was higher.
I don't know what adjustments are available, but I do know that I can produce images that look that different on the same television whether it be a CRT, LCD, or plasma.
It's also possible to edit any photo and make it look over developed or underdeveloped.
The background on the Lowrance is much lighter than that on the Humminbird which is nearly black. The contrasting bright areas on the Humminbird look like neon compared to those on the Lowrance.
The image on the Lowrance is definitely better as posted, but is that the result of differences in adjustment?
I Love BassResource reply :
No, this is just a single example, and wasn't meant as a bash, just as an example of the current "state" of each. Examples such as this are plentiful, this isn't an exception to the rule.
As I've stated, I would assume each will get better with scheduled software updates.

They could win millions with a counter suit. I bet it's all settled without any of us ever knowing the results. They both will continue to produce, market, and sell the idea.
